Gran Canarian plant life
Our goal was to record more than 600 different plant species on Gran Canaria. I am sorry to say that we failed; we did not get any further than 576. We noticed that there hadn't been much rain this year, so the island was much drier than usual. This probably had an effect on the number of species we could identify. Nevertheless, we were satisfied with the species we recorded. There were some new recordings for the island and we found many endemics as well.

Report of this BotanicalJourney
7 and 9 March 2012: The surroundings of Moya and Carreteria (Google Map)
The first day of our
BotanicalJourney we arrived at our holiday-home which was adjacent
to the church in the town of Moya, on the north of Gran Canaria.
It was already getting dark when we arrived, but nevertheless we
made a small walk to warm ourselves up a bit and to get started
with our species list. Two days later we repeated our walk during
daylight and extended it towards the town of Carreteria. One of
the first findings was Cyrtomium falcatum, a rare specie
for the Netherlands, but in Moya we found it on a wall in the
middle of the village.
The walk through the village produced several species that are
very common to Gran Ganaria, such as Anagallis arvensis, Aster
squamatus, Echium decaisnei, Malva nicaeensis, Pericallis
webbii, Rumex lunaria and Stachys ocymastrum. In
Moya Cardospermum grandiflorum (see picture) was VERY
abundant. This garden-escapee covered almost every barren field we
could find. There were more garden-escapees to be found, like Aptenia
cordifolia, Cyperus rotundus and Ipomoea indica. Fortunately
we also found some fallow fields with typical species such as Amaranthus
hybridus, Amaranthus retroflexus and Picris echioides.
Scattered through the village there were concrete tanks which
apparently had been used in the past to collect rain water. They
looked disused now and were almost dry. However some of them
seemed to contain a little water permanently. There we found
species of wet habitats like Typha domingensis and Lemna
minor. The barranco between Moya and Carreteria could be
crossed via a narrow footpath but this produced almost no other
species than Arundo donax.
8 March 2012: Km 4 at the GC-75 from Moya to the coast (Google Map)
The next day we decided to go to the coast. So we drove down hill
to the north of Moya. On two locations we parked our car next to
the road GC-75 to look for plants. Both of the locations were not
particularly interesting, but nevertheless we recorded some nice
plant species. On the first location we found some decorative
plants, like Convolvulus floridus, Campylanthus salsoloides
and Fagonia cretica (see picture). The second stop was at
the junction with the GC-752, where we found Aizoon
canariense, Heliotropium ramosissimum, Volutaria canariensis
and both Mesembryanthemum crystallinum and Mesembryanthemum
nodiflorum.
8 March 2012: Coast at San Felipe (Google Map)
The coast at San Felipe, north of Moya, is threatened by the sea:
waves smash onto the coast with great strength. The boulevard is
falling slowly into the sea as a result of it, but nevertheless
the municipality tries to make something nice of it. We found Astydamia
latifolia on the boulevard. At the west end of the
boulevard we climbed across the remains of this boulevard and
entered a small foot path along the shore. There was a significant
salt spray, as the plants clearly indicated: Bassia tomentosa,
Lycium intricatum, Salsola oratovensis (see picture) and Zygophyllum
fontanesii were all near the shore. We had to use the
identification key written by Hohenester to identify Limonium
sinuatum and L. pectinatum, but in the end we
managed to do so. A little higher on the cliffs was some sort of
ancient field, near the remains of an old farm (?). Here, where
the direct influence of the salt spray was a little bit less, we
found Euphorbia aphylla, Ononis angustissima, Nauplius
graveolens ssp. odorus and Schizogyne sericea. The
area was dry and rocky.
8 March 2012: Amagro mountain (Google Map)
We had read somewhere that the Amagro mountain near the town of
Gáldar was a good place to localize Sideritis amagroi. You
would think it isn't so difficult to find that specie, but
unfortunately, we were not able to find it. We accessed the hill
from the parking-area near a school and climbed up following a
small stream. At first we passed a banana-farm but after that we
climbed up the hill all the way. Although we didn't find that
specific Sideritis, we did find several other nice plants
like Asphodelus aestivus, A. tenuifolius, Calendula arvensis,
Kickxia elatine, Kickxia scoparia, Lavandula multifida subsp.
canariensis, Lobularia canariensis and Scolymus
maculatus. One of the nicest plants however was Ceropegia
fusca (see picture). Some trees and shrubs were present in
the higher parts of the mountain, mainly Juniperus turbinata
and Pinus canariensis, while several other species were
planted in large numbers: for example Dracaena draco,
Euphorbia canariensis and E. aphylla. In the shadow
underneath some rocks we discovered Habenaria tridactylites and
Scilla haemorrhoidalis (both without flowers but
recognizable nevertheless). This was a very successful walk with
breathtaking views over the ocean and numerous new plant species.
8 March 2012: Alongside the GC-700 west of Moya (Google Map)
When we drove back from Gáldar to Moya, we followed the GC-700.
About half way we stopped at a mini-barranco without a name just
before a curve in the road. We found Ageratina adenophora,
Aichryson laxum, Arisarum vulgare, Bidens pilosa, Briza minor,
Dracunculus canariensis, Evax pygmaea, Gnaphalium luteo-album,
Trifolium subterraneum and several other species here. We
also found a plant we identified as Sipthorpia europea,
although the leaves seamed unusually smooth-edged. For further
identification purposes we collected a voucher specimen, which
will be sent to the public herbarium of the National Botanic
Garden of Belgium.
9 March 2012: Los Tilos - Barranco de los Propios (Google Map)
Laurisilva is without any doubt the most interesting habitat of the Canary Islands. Unfortunately most of the original forests have disappeared in the last decennia due to all kinds of human influences. Calculations have been made that suggest that the current area of Laurisilva is less than 2% of the original surface. This is a shame. Fortunately the most intact pieces of Laurisilva are protected by law nowadays. At Los Tilos there is a visitor centre and a path which guides you through the Laurisilva. We will come to that later, because stubborn as we are, we refused to follow that path at first. A little to the north you can find the Barranco de los Propios. This is a Barranco without guided tours and marked paths. There is however a small path, which is easy to follow. It will lead you to several very nice plant species characteristic to Laurisilva.
Back
in 1967 Johannes Lid wrote an interesting report on the
Laurisilvas of Gran Canaria. According to this author you can
define a forest as Laurisilva if it contains the following
species: Ocotea foetens, Persea indica, Apollonias barbujana and
Laurus novocanariensis. Well, Barranco de los Propios has
them all! Underneath the trees this Barranco offers you Hypericum
canariense, Hypericum reflexum, Ranunculus cortusifolius, Semele
androgyna var. gayae, Smilax canariensis and Vinca
major. But best of all: Canarina canariensis (see
picture) in large numbers! Halfway along the path there was an
open but damp place with Anagallis arvensis, Fumaria coccinea,
Myosotis latifolia and Ranunculus sardous.
9 March 2012: Los Tilos - Barranco del Laurel (Google Map)
OK - we found the real thing by ourselves, but we couldn't pass
the Barranco del Laurel without following the path. It was very...
well... "educational". We admit we learned new species because of
the signs with species names that were everywhere, but seeing a
planted Isoplexis chalcantha with a clear sign next to it
is not the same as discovering it in some abandoned forest by your
own. However Barranco del Laurel proved to be our only chance to
see Solanum lidii (see picture), a very rare endemic
specie that is planted in Barranco del Lauro in large numbers.
Sometimes it was impossible to establish whether a specie was wild
or planted.
In this somewhat confusing circumstances we recorded Aeonium
arboreum, Convolvulus siculus, Dendriopoterium menendezii,
Echium callithyrsum (see picture), Geranium canariense,
Gesnouinia arborea, Ixanthus viscosus, Sideritis discolor
and Sonchus canariensis. In Laurisilvas many ferns can be
found. It is unlikely that ferns are planted there - even in the
Barranco del Laurel. So here is an impression of the ferns we
found: Adiantum reniforme, Anogramma leptophylla, Asplenium
hemionitis, Asplenium onopteris and Cheilanthes
maderensis.
9 March 2012: Los Tilos - Camino Casa Encamada (Google Map)
We tried our luck south of the marked path through the
Laurisilva, curious as we were to maybe find some more Laurisilva
remains. But unfortunately this was not the case. For now Barranco
los Propios was the nicest Laurisilva we found. For now. But we
will come back to that later (save the best for last, they say).
At Camino Casa Encamada we found some new species of which we will
mention only Drusa glandulosa and Lavatera cretica
here.
10 March 2012: Caldera de Bandama (Google Map)
The Caldera de Bandama is part of the Tafira Protected Landscape
and is a location of both geological and botanical interest. The
caldera is about 1,000 m wide and 200 m deep. The slopes consist
of various types of volcanic stones and ashes. One of the many
good reasons to go there is the occurrence of Parolinia
glabriuscula at the bottom of the caldera. We were very
anxious to see this specie and indeed we found it. We also
recorded Allagopappus dichotomus, Bosea yervamora, Lavatera
acerifolia (see picture), Olea cerasiformis and Retama
monosperma in the Caldera de Bandama. The large palm trees
were covered with Davallia canariensis.
10 March 2012: Punta de Jiramar (Google Map)
Punta de Jiramar is a location
you probably wouldn't visit if nobody told you that it is worth
it. Believe us: it is. We parked our car at the back of a large
commercial centre and followed the coast line. Soon we entered a
sort of valley where a Barranco came to the sea. There were some
concrete structures there, suggesting a flow of sewer water in wet
times as we could smell very clearly. The nice thing about this
location was that there were several plant species typical for
areas with salt spray, like Argyranthemum frutescens,
Frankenia boissieri, Sarcocornia fruticosa, Suaeda mollis
and Traganum moquinii, but also plants of more ruderal
inland habitats such as Asteriscus sericeus, Datura innoxia,
Moricandia arvensis and Xanthium spinosum. There
were two species on this location we found hard to identify. But
we were able to do so afterwards, thanks to the pictures we took.
The first turned out to be Sclerophylax spinescens (see
picture). The other plant of which identification was troublesome
at first was a strange fleshy plant that turned out to be Heliotropium
curassavicum. This specie is recently described as a new
neophyte for Gran Canaria by Filip Verloove, who found it on 3
places. His paper helped us to identify our plant.
10 March 2012: Tufia (Google Map)
Another location on the east coast of Gran Canaria. On this
peninsula we hoped to find Convolvolus caput-medusae and
Atractylis preauxiana. Unfortunately we didn't. The most
interesting spot on the Tufia peninsula was an archaeological site
which was closed off by a very high fence. The area was therefore
inaccessible for good citizens like ourselves. On the peninsula
almost no plants were present; it was only rock and ashes. However
we managed to find three species that were new to our list: Amaranthus
deflexus, Cyperus capitatus and Launaea nudicaulis.
10 March 2012: Around the lighthouse of Arinaga (Google Map)
We went to Arinaga with the specific goal to find Lotus
arinagensis. This time we succeeded! The area looked to us
like we expect the landscape on the moon to be: cold, windy, rocky
and dry. There were hardly any plants at all! You will be
surprised how difficult it is to find a small plant like Lotus
arinagensis in circumstances like this, but as we said, we
managed quite well. You can see the result in the photo. Another
good thing was that we discovered Atractylis preauxiana here.
This is one of the species we failed to recognize in Tufia. So the
visit to the lighthouse of Arinaga was very worthwile.
10 March 2012: Barranco de Guayadeque (Google Map)
At the end of the day we followed the road to Aguïmes and the road
further west into the Barranco de Guayadeque. We stopped at
several locations. Just west of Aguïmes we found Lotus
sessilifolius and Salvia canariensis (see picture)
and further on we discovered Crambe pritzelii, Teline
microphylla, Erucastrum cardaminoides and Descurainia
preauxiana. But by that time it was getting pretty dark, so
we decided to head back to our house in Moya.
11 March 2012: Barranco de Agaete near San Pedro (Google Map)
The next day we made a trip to the surroundings of Parque Natural
de Tamabada. We stopped at several locations. The first was the
Barranco de Agaete near San Pedro. We parked our car and followed
the road GC-231 by foot for a while. There were steep rocky slopes
with some pine trees here and there. First we found several
specimens of Scilla haemorrhidales with beautiful flowers.
Right next to the Scillas we found a plant which was difficult to
identify at first. Finally we discovered that it was Dipcadi
serotinum (see picture). A nice plant to find! Furthermore
we found Astragalus pelecinus, Medicago littoralis, Pancratium
canariense and Vicia filicaulis. At a damp place we
found Samolus valerandi and Scirpus supinus as
well.
11 March 2012: Alongside the GC-200 north of El Risco (Google Map)
We followed the GC-200 and stopped at several locations, mostly at
Barranco's, dried up water streams or any other location that
seemed suitable to find new species for our list. South of Agaete
we found Eragrostis barrelieri and near the Barronco
Guyaydra we found Herniaria cinerea, Matthiola bolleana subsp.
morocera (see picture), Orobanche ramosa and Reseda
lancerotae. North of El Risco we stopped at a place where
the rocky slopes were very steep. We followed the road by foot for
a while to examine the plant species that were growing on the
steep cliffs. Right next to the road we found Calendula
bicolor, Carduus baeocephalus, Erodium chium and both Plantago
afra and P. aschersonii (which is regarded to be a
synonym of P. coronopus nowadays). A little more away from
the traffic, but sometimes not easy to reach, we identified Allagopappus
viscosissimus, Cheirolophus falcisectus and Lotus
lancerottensis.
11 March 2012: Barranco Guyguy alongside the GC-200 south of El Risco (Google Map)
South of El Risco the Barranco Guguy offers some rocky cliffs with
several nice plant species. Most of them were not new to our list,
but right next to the road we managed to find inconspicuous
species like Monanthes brachycaulos and Suteria
canariensis as well as plants with more decorative value,
such as Babcockia platylepis/Sonchus platylepis and Cynara
cardunculus. A little further to the south we stopped at a
place called Andén Verde, which offered stunning views over the
ocean and some of the valleys of Gran Canaria. We found
Epilobium tetragonum and Lotus lancerotensis here,
but also several plant species we were already familiar with, like
Euphorbia regis-jubae, Euphorbia canariensis and Euphorbia
aphylla (see picture).
11 March 2012: Barranco Presa (GC-210) (Google Map)
East of San Nicolás de Tolentino we followed the GC-210 towards
some artificial lakes. This road lead through the Barranco Presa.
It was a narrow road and we were lucky that there was not much
traffic: it was sometimes impossible to park the car so we had to
stop in the middle of the road. This was the case when we spotted
Calotropis procera, a plant of well over 2 meters height
which we couldn't identify at first (see picture). Luckily we were
able to establish the name a few weeks later thanks to the
pictures we took of the plant. We also found Campanula erinus,
Chrysoprenanthes pendula, Lagurus ovatus, Micromeria tenuis,
Paronychia argentea, Petrorhagia velutina and Phagnalon
purpurascens in the Barranco Presa. In the Barranco we found
a small but very deep pond with Goldfish in it and a large
dragonfly hovering above it.
11 March 2012: GC-21 near Artenara (Google Map)
A little north of Artenara we stopped alongside the GC-21 because
we noticed Aeonium simsii and Aichryson punctatum growing
on a cliff next to the road. On closer look we also found Umbilicus
heylandianus there as well as Sagina procumbens and
Solanum alatum. A little further at a location named Paso
Blanco we noticed Orchis canariensis (of which some people
say it is Orchis patens subsp. canariensis) next to the
road (see picture). There were several species of them in a narrow
and nameless barranco. We found also found Erysimum bicolor,
Greenovia aurea and Mentha longifolia there.
12 March 2012: Fontanales (Google Map)
From what we had seen of the Gran Canarian flora until now we
concluded that the surroundings of Fontanales were by far the most
interesting location for finding new plant species. So we decided
to make a longer walk there. We started in the village of
Fontanales and checked out the surroundings of the church, where
we found several new species like Andryala pinnatifida. Then
we followed a path towards the sporting area (tennis) where we
found Adenocarpus foliosus, Silybum marianum and many
other new species. We continued to follow that road up the hill.
About half way we found Salvia microphylla (of which we
first thought it might be Salvia coccinea, but we were
wrong about that). At the highest point of our walk, there were
many specimens of Romulea columnae (see picture). On the
way down into the valley we noticed that Senecio mikanoides
(a.k.a. Delairea odorata) was very abundant and covering
large semi-human influenced areas.
11 and 12 March 2012: Paso Blanco (west of Artenara) (Google Map)
Yesterday we were pleasantly surprised by the flora of Paso
Blanco, like Orchis canariensis. Because we were there at
the end of the day while it was almost dark, we decided to go back
there. We tried to follow a path up the small barranco but that
proved not to be an easy task. Parts of the hill had suffered from
landslides so some parts were just inaccessible. Nevertheless we
managed to find some species that had been overlooked the previous
day: Lathyrus setifolius, Neotinea maculata, Pterocephalus
dumetorum, Tanacetum ptarmiciflorum and Veronica
hederifolia.
12 March 2012: Tamabada (Google Map)
Pinar de Tamabada is an Natural Park. On Gran Canaria it is very
remarkable that forests are high up the hills, whereas the lower
altitudes are almost treeless. Tamabada is one of the few places
where you can find a proper forest. Most of the trees are pine
trees. There are also vast areas covered with Cistus
monspeliensis and Cistus symphytifolius. We
searched for Citinus species as well, but unfortunately we
didn't succeed in that. We did find three different Micromeria
species however: Micromeria benthamii, Micromeria lanata and
Micromeria pineolens. Another known specie from Tamabada
is Isoplexis isabelliana. Because it is not planted there
(we hope), the finding was more rewarding than the Isoplexis in
the Barranco del Laurel, which we described earlier. The location
of this Isoplexis is easy to find: just park your car at
the picnic area and walk around. You can't miss it, because it is
right next to the path.
12 March 2012: alongside the GC-210 between Artenara and Tejeda (Google Map)
The GC-210 again was one of these roads on which you can't really
park a car. The views over the mountain ridges were stunning
however, and luckily we managed to find a very small space in
which we could squeeze our car. The view was the main reason to
stop here but of course we looked for plant species as well. This
resulted in the finding of Carlina canariensis and Juncus
articulatus. A Lavandula specie proved to be hard to
identify. However, due to the characteristic shape of the leaves
we managed to make a positive identification of Lavandula
minutolii (see picture).
13 March 2012: San Gregorio near Le Román (Google Map)
San Gregorio is located southwest of Las Palmas. An unpaved road
leaves the town of San Lorenzo and heads west. We followed that
road, leaving the small ponds behind us to visit at a later
moment. Some large specimens of Salvia canariensis were
present there (see picture). We zig-zagged somewhat across the
hill, and found ourselves in yet another large-scale anti-erosion
project: large numbers of (endemic) plant species had been planted
here recently. We came across a fence with some signs asking us
not to enter the area behind it. Naturally, we obeyed the request
and walked all the way around the fence. On the other side were
the remains of what once had been a pond. A small muddy pool was
the only thing that was present at that time, but from a distance
we could see a vaguely green color on the edges of the water. Some
goats were drinking from the water and eating from the green
color. Reason for us to go there, of course. We had to lay flat on
the ground to be able to identify some of the plants here, because
they were really small. Some of the species were Amaranthus
blitum ssp. emarginatus, Coronopus squamatus, Verbena supina and
Chamaesyce serpens. There was also a very tiny version of Cyperus
pygmaeus present.
The next plant was a bit of a puzzle. It looked like a pink
flowered Lythrum at first glance but it had big sepals
and it was way to hairy. Thanks to the excellent work on the
Canarian Flora and vegetation of Per Sunding we were pointed in
the right direction. Sunding describes the plant community Verbenetum
supinae in his Vegetation of Gran Canaria
(1972). G. Kunkel had taken him to some dried up basins in
the vincinity of Tamaraceite, back in 1966. It was the first time
a plant named Petunia parviflora was mentoined for the
Canary Islands. The plant originates from South America. For
certain this was also the plant we found (see picture). The name
of the plant community is based on the plant Verbena supina,
which we found in considerable numbers. So we definitely were on
the good spot.
We followed our way back over the hill, at first following an old
water ditch. There was one tree present: it proved to be Quercus
suber. Zig-zagging across the hill, we found Asparagus
pastorianus, Centaurea calcitrapa and Euphorbia sulcata.
Back at San Lorenzo we looked at the dried out basins we saw
earlier. Some typical species here were Aster squamatus,
Chenopodium anthelminticum (recently described by F.
Verloove for Gran Canaria), Portulaca oleracea (s.l.),
Gnaphalium luteo-album, Cyperus eragrostis, Lythrum junceum and
Amaranthus blitum subsp. emarginatus. Unfortunately we
scared the hell out of a group of 20 Night herons (Nycticorax
nycticorax) who flew up into the air in great panic, making
a lot of noise.
13 March 2012: Las Palmas GC near Collegio San Vincente de Paúl (Google Map)
On Google Maps we discovered a large barranco in Las Palmas, so
we went there to check it out. This proved to be a big mistake:
the Barranco was intensively used for all kinds of human
activities, of which leaving waste was one of the less smelly. So
we turned around and tried to leave the city as quickly as we
could (which was not an easy task). Near Collegio San Vincente de
Paúl we recorded some new species: Amaranthus muricatus,
Festuca arundinacea, Pennisetum clandestinum and Spergula
pentandra. Hip Hurray.
13 March 2012: San Andrés (Google Map)
On our way home we decided to
stop in San Andrés. This is a town that is very close to a
highway. You can't really miss San Andrés because probably you
have to wait for one of the pedestrian crossings when you pass it.
At first we walked to the sea. There were no new plants present,
and it was a rather uncomfortable place to be because of the heavy
winds (which lead to impressive waves and an even more impressive
salt spray). So we crossed the road and followed a small road up
into the hills. We soon found out that a large part of the valley
going south from San Andrés had been transformed into a banana
orchard. By the looks of it the orchard was very much
industrialized and impossible to enter. But there was a foot path
going up the hill slopes at the eastern side of the valley. We
followed that path, leading us to some old and not very well
maintained banana orchards. We found some nice weed species there,
like Arenaria leptoclados. Higher up the hill we found the
more typical vegetation of the dry, rocky and erosive hills on
Gran Canaria. For example there was a very nice specimen of Aeonium
canariense ssp virgineum fully in flowers (see picture). We
also found Aloe vera and -my favorite- Ceratopegia
fusca. On the rocks Astydamia latifolia was present
and on the path we found Asteriscus aquaticus. We
continued our route along a water canal, where we found Thevetia
peruviana (= Cascabela thevetia) abundantly present. Through
a poorly maintained banana field we descended. On a wall next to
the main road we found Hyoscyamus albus.
14 March 2012: Near Tenisas (Google Map)
The next day we intended to go to the centre of Gran Canaria. We
first drove to the south and left the highway at Arinaga. From
there on we went northwest, following the GC-65. We stopped our
car at the Barranco Cuevas Blancas because we thought we saw some
water. Since this fluid is scarce on Gran Ganaria, it is always a
good idea to check wet areas for plant species. Although the area
wasn't particularly scenic we managed to find some new species
next to a small stream: Tanacetum ferulaceum and Veronica
anagallis-aquatica. In more dry habitats Tricholaena
teneriffae and Echium onosmifolium were present.
When we continued our journey we accidentally turned into the
GC-550 towards the town of Tenisas. We soon realized that the area
became much too dry to find some new plant species, so we turned
around. At that point we saw Anchusa italica (=Anchusa azurea)
and Tragopogon porrifolius (see picture). On closer
look, we also managed to find Carduus pycnocephalus and Cichorium
endivia here. As you can tell from these species: the area
can be characterized in one word: DRY!
14 March 2012: Pico de las Nieves (Google Map)
We had heard from the "white rock" or "Risco Blanco" in the area
of La Culata. We hoped to find some calcareous plant species there
so we followed the GC-654. This was a very narrow road but people
in traffic were friendly and relaxed. The road forms a circle, so
it doesn't really matter if you follow it clockwise or the other
way around. We soon found out that the Risco Blanco was not easy
accessible and stopped at the most northern point of the road.
From there on we followed an even narrower road up north, which
finally ended at some houses. We recorded Alcea rosea,
Colocasia esculenta, Ruta chalepensis and Tolpis
lagopoda here. We continued our route towards the Pico de
las Nieves and stopped at Paso herradura, where we recorded Micromeria
helianthemifolia, and at Llanos de Pez, where we found Sideritis
dasygnaphala and Verbascum virgatum. Finally we
reached the military base at Pico de las Nieves, where we recorded
Urtica stachyoides and Erysimum bicolor (see
picture). We drove up as far as we could and ended at a rocky area
with a former military lookout. The area was well covered with Argyranthemum
adauctum. When we descended we saw a large fence with Narcissus
tazetta and Scilla dasyantha (= Scilla haemorrhoidalis).
14 March 2012: Junction of gc230 and gc400 west of Arinez (Google Map)
It was getting a little bit dark already when we discovered a rock
next to the road somewhere west of Arinez. This rock was covered
with many different Aeonium, Aichryson and Greenovia
species, so this gave us an opportunity to look closely at the
differences between the species. We recorded Aeonium
undulatum, Aeonium percarneum, Aichryson punctatum and Greenovia
aurea (see picture). Furthermore we found several ferns like
Asplenium adiantum-nigrum, Asplenium obovatum and Asplenium
trichomanes. Also Trifolium stellatum and Vicia
hirsuta were present here. We identified a Tanacetum as
T. oshanahanii, but one of the visitors to our site told us
that the occurrence of this specie is limited to Guayedra. So our
identification is probably wrong; it might not be Tanacetum at
all, but Argyranthemum... (thanks for letting us know,
André).
15 March 2012: Maspalomas (Google Map)
The dunes of Maspalomas are famous. Not only because they are the
only dunes on Gran Canaria but also because they are truly
spectactular. The sand dunes have typical curved forms due to the
winds and they keep forming when you stand there: sand particles
fly into your hair, your clothes, your bag and your camera. But
nevertheless it is worthwhile to go there. Especially if you
manage to find some places where there is a little less influence
from the wind and a vegetation community has been able to form.
The plant species present are well adjusted to the extreme
circumstances (apart from the winds there is a continuous lack of
rain water). One of the most spectacular species is Neurada
procumbens (see picture), also known as "camel plant". This
specie forms seeds which are very prickly and attach themselves to
almost everything. In the Sahara desert the seeds are spread by
the feet of camels. When we left the beach we found that there
were several seeds stuck to our shoes as well! Other species in
this surreal environment were Ononis serrata, Limonium
tuberculatum, Neatostema apulum and Salsola kali.
In more sheltered areas we found Argyranthemum filifolium,
Frankenia pulverulenta and Turnera ulmifolia.
15 March 2012: Barranco de Arguineguin (Google Map)
The Barranco de Arguineguin is
situated west of Maspalomas. This barranco is very dry but famous
for its population of endemic Dragon Trees (Dracaena
tamaranae). Unfortunately we missed this specie. We did
record some other shrub species: Heliotropium
messerschmidioides and Convolvulus glandulosus (see
picture) could be found next to the road. We also found Euphorbia
serrata, Argyranthemum filifolium and Parolinia ornata.
In the dry valley sometimes water could be found in man-made
canals. In one of these places we recorded Potamogeton
nodosus. West of Soria we found Cistus symphytifolius
subsp. leucophyllus.
15 March 2012: Barranco de Mogán (Google Map)
The Mogán valley is said to be more arid than the Arguineguin
valley. This might be the case, but it didn't provide us with many
new species. Asteriscus graveolens ssp. stenophyllus was
in fact the only one.
15
March 2012: GC-60 north of Arteara (Google
Map)
The Barranco through which the GC-60 leads is more arid as well.
We recorded Bupleurum salicifolium and Ruta oreojasme
(see picture) here.
15 March 2012: Rock Bentayga (Google Map)
For plant hunters the Rock Bentayga is a well-known place. It is
rich in endemic plant species and one of the very few locations on
Gran Canaria where Crambe scoparia can be found. It is
not hard to find: just follow the foot path from the road to the
rock and you can't really miss it. When we were there, the place
was very crowded with people putting up tents to see a next day's
racing event. A part from Crambe scoparia we didn't find
any new plants for our list but we did harvest a large bag of Prunus
dulcis almonds. They were delicious to eat and we even
brought a large quantity home (which was highly appreciated).
16 March 2012: Barranco Virgin / Barranco Obscuro (Google Map)
The last day of our visit to Gran Canaria was supposed to be the
most spectacular for us. That is why we saved a visit to a
Laurisilva for the 16th of March. As we previously have pointed
out, Laurisilva is one of the most rich habitats of Gran Canaria
which unfortunately is affected largely by human activities. The
remaining parts are protected well - and for a good reason too! We
went to the Barranco Virgin, parked our car in a village and
followed the barranco by foot. It contained all the species that
make it a Laurisilva: Ocotea foetens, Persea indica,
Apollonias barbujana and Laurus novocanariensis. We
also found Hedera canariensis (see picture). Some of the
herbs in the valley were Bartsia trixago, Hypericum
canariense, Bystropogon canariensis, Plantago arborescens,
Senecio teneriffae, Limonium pectinatum, Galactites tomentosa,
Echium callithyrsum, Pericallis webbii and Aichryson
laxum. At damp places we found Carex paniculata, Conium
maculatum and Wahlenbergia lobelioides. Other nice
species were Bystropogon canariensis, Plantago arborescens and
Senecio teneriffae.
The valley was not fully covered with forests. In fact, large
parts were used for minor-scale agriculture. This provided us with
species like Kickxia commutata (see picture), Medicago
arabica, Galium scabrum, Papaver rhoeas, Moehringia pentandra
and Paronychia canariensis. Near gardens we found many
escaped plant species such as Agapanthus praecox, Aloe
saponaria, Austrocylindropuntia subulata, Freesia refracta,
Podranea ricasoliana and Solandra grandiflora.
Probably they can be a threat to wild plant species? It was
unclear to us if the specimen of Dracaena draco that we
saw was wild or not.
One of the best preserved remains of Laurisilva can be found in
the Barranco Obscuro. It is not very well accessible, but with a
little help we managed to enter the forest. We had to descend the
hill slopes using hand and feet, but it was worth the trouble. It
was truly a Laurisilva-by-the-book, complete with Canarina
canariensis. And so the Barranco Obscuro was a good place to
end our BotanicalJourney on Gran Canaria!
Some comments on the recording of new species for Gran Canaria
The orginal flora and certainly the endemic plant species are
well known on Gran Canaria. Maybe we found some of these plants on
new spots. However we do not know the island and its flora, nor
the efforts of other botanists, well enough to claim this. We
could construct a list of the known flora of Gran Canaria
combining Listada de especies silvestres de Canarias 2009
(hereafter; Listada), distribution records from Hohenester /
Welss' Exkursionsflora für die Kanarischen Inseln and P.
And I. Schönfelder's Die Kosmos Kanarenflora, edition
1997. On Gran Canaria a lot of plants are brought to the island by
people. These species do not belong to the wild flora. It is of
these plants we could note some 'new' records. A couple of them
were earlier considered new to Gran Canaria and they are described
by Filip Verloove in New xenophytes from Gran Canaria,
2012.
Agave
attenuata
Already known as a cultivated specie in the Canaries and recently
described by Filip Verloove as a new neophyte for Gran Canaria. We
found this specie on several places. Our first record was at Moya
in a dried out basin.
Aloe
maculata (syn. Aloe saponaria)
In the Barranco Virgin, in the riverbed near the road in the
middle of the barranco we found a lot of escaped plant species. Aloe
maculata seemed to be new to the Island. It is easily
distinguised from Aloe vera by its white spotted leaves.
It was only found escaped on Tenerife (Hohenester / Welss), but
the specie is not mentoined in the Listada.
Ampelodesmos
mauretanica cf.
We found one specimen in a flat riverbed close to the sea near
Jiramar. The specie is probably also planted nearby.
Austrocylindropuntia subulata
In a road margin at Barranco Virgin. Found on the last day of our
stay. We thought we had seen it before but payed no attention to
it due to its resemblence with a small Opuntia.
Carex paniculata
In Hohenester/Welss we found a doubtful record of this plant for
Gran Canaria, but we are certain we found the specie at the nature
reserve Barranco Obscuro. It may have been named incorrectly by
Per Sunding who described this forest in detail in The
Vegetation of Gran Canaria (1972) and noted Carex
vulpina. This specie is not accepted or named in any other
plant list of Gran Canaria. Our plant was growing in a small
cluster, had small leaves (4 mm), a long inflorescens (10-15 cm)
and blackish fruits. The stem was sharpely triangular and rough on
the top. The plant is not collected because we only saw one
specimen.
Chenopodium anthelminticum
Recently described as a new neophyt for Gran Canaria by Filip
Verloove. It looks like a Chenopodium ambrosioides. We saw
this plant on several places. Our first record was on the bottom
of the Caldera de Bandama.
Echium
simplex
Just outside the nature reserve Barranco Obscuro near a garden. We
found a record in Hohenester/Welss. It is not named in Listada
de especies silvestres de Canarias (2009) for Gran Canria,
so maybe this is a new record. We think the plant maybe is escaped
from the nearby garden.
Festuca arundinacea
Lawn weed at Las Palmas together with lots of Medicago
lupulina. A voucher specimen of this plant shall be given to
the public herbarium of the National Botanic Garden of Belgium.
Filago minima = Logfia minima
In an heavily grazed meadow south of Fontanales. Mixed with other
tiny plants like Romulea columnae, Myosotis discolor and Cotula
australis.
Helianthus annuus
In a extensive Banana-plantation with lots of other weeds.
Heliotropium curassavicum
We found 1 plant in a flat riverbed close to the sea near Jiramar.
It was a strange fleshy plant which we could not name for some
time. The specie is also recently described as a new neophyt for
Gran Canaria by Filip Verloove, who found it on 3 places. His
paper helped us to indentify our plant.
Jasminum officinale
In Maspolamas on the edge of a garden, growing over native plants.
Lathyrus setifolius cf.
We could not find records for Gran Canaria. The specie is already
known from Tenerife. We found it in a road margin at Paso Blanco,
west of Artenara.
Lonicera etrusca
We found this specie in Moya on a wasteland in the village. A
voucher specimen of this plant shall be given to the public
herbarium of the National Botanic Garden of Belgium.
Medicago lupulina
Growing in large numbers as a lawn weed on several places at Las
Palmas and Maspalomas. In Las Palmas it was growing together with
Festuca arundinacea. A voucher specimen of this plant shall
be given to the public herbarium of the National Botanic Garden of
Belgium.
Podranea ricasoliana
Big area (25 x 25 meter) in a riverbed near the village
Valsendero (Barranco Virgen). Probably naturalized and escaped
from a nearby garden.
Physalis peruviana
We found several specimens in a flat riverbed close to the sea
near Jiramar. Sewage sludge was nearby, whisch probably
contributed to the distribution of this plant. It is known for its
edible fruits. The specie is also recently described by Filip
Verloove as a new neophyt for Gran Canaria.
Salvia
microphylla
We found 1 plant south of Fontanales. We called it at first Salvia
coccinea, based on its red flowers and the identification in
the exkusionsflora. Salvia microphylla is not named by
Hohenester/Welss. Filip Verloove described this specie as a new
neophyt for Gran Canaria, not coincidentally also found near
Fontanales. Filip saw our photo's and concluded we found the same
specie.
Thevetia
peruviana
Escaped from a nearby garden in the Barranco Virgen.
Turnera ulmifolia
At Maspalomas in plantbeds, in pavement cracks and on walls. The
specie is also recently described by Filip Verloove as a new
neophyt for Gran Canaria.
List of the recorded plant species
PLEASE NOTE:
Only the first finding of species is displayed. So species that
were recorded, let's say, both on the 13th and the 15th of March
ONLY are noted on the 13th.
