118 Botanical Notices from Spain. 
Cerastium repens, L., Piilotrichum longicaule, Boiss., &c. From 
Cerro Tesoro I descended to the Cartejuela, where there are several 
springs,— a rare occurrence in these frightfully arid limestone alps. 
With the exception of a few very scattered specimens of Vicia lutea, 
L., and Hypericum hyssopifolium, L., there was scarcely anything of 
importance to be found; in May the vegetation may be more inter- 
esting. In that part which hes at the foot of the Trevenque, whose 
immense cone rises here proudly, the Adenocarpus decorticans 18, as 
I have said, very common ; besides this, the Juniperus Sabina, L., and 
Arctostaphylos Uva-ursi grow in great abundance, as well as Bupleu- 
rum spinosum, L. fil., which is found very abundant on many spots 
of the limestone portion of the Sierra, and grows as low down as 
3000 feet and more. 
At length we gained the base of the cone of the Cerro Trevenque, 
the ascent of which I undertook from the east side. This, as well 
as the western declivity, is almost wholly filled with steep rocks and 
boulders of limestone, and it was often necessary to dig out steps in 
the soft limestone sand to get a firm footing. Notwithstanding these 
circumstances, so unfavourable to vegetation, the rarest plants are 
found on this very side, as for instance, Scabiosa pulsatilloides ; Boiss., 
Helianthemum pannosum, Boiss., Santolina elegans, Boiss. (the only 
locality for this plant hitherto known is the Trevenque, and even 
here it is rare), Convolvulus nitidus, Boiss., Anthyllis tejedensis, Boiss., 
Ononis cephalotes, Boiss. On the highest summit, from whence there 
is an indescribably beautiful view over the whole limestone alps, as 
well as the charming Vega of Granada as far as the Sierra Morena, 
no plants worthy of mention grow, except the Cotoneaster grana- 
tensis, Boiss., and some trees of Pinus sylvestris. ‘The whole north- 
ern declivity is covered with Arctostaphylos Uva-ursi. 
Excepting these spots, which are distinguished by rare plants, 
the vegetation of the limestone range is throughout very uniform. 
As far as the warm region extends, the hills and mountains are 
covered with the same plants which I have already mentioned in the 
environs of Granada. The Berberis vulgaris, var. australis, charac- 
terizes the mountain region, and extends into the alpine region, and 
is everywhere common, especially on arid sunny spets. Besides this, 
the Salvia officinalis, L., together with another species of this genus 
clothed with a thick white wool, Santolina rosmarinifolia, Mill., 
Helichryson serotinum, Boiss., Daphne Gnidium, L., Lavandula lanata, 
Boiss., an Andryala and a Thymus are the principal constituents of 
this mountain flora. The Jnula montana?, the beautiful Hchium 
albicans, Lag., and others, are limited to some localities. Of 
Cryptogamia, beside some few mosses and liverworts, some Alge 
and Aspidium nevadense, Boiss., there are only lichens, apparently in 
great quantity, especially of the genera Parmelia, Lecidea and Ver- 
rucaria. 
No. V. Gursar DE La Sierra, September 5. 
Since the middle of August I have been staying in this village, 
which is situated in the valley of the Jenil, about 3000 feet above
