Cerastium repens, L., Ptilotrichum 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., ^xi^ Hypericum hyssopifoUum, L., there was scarcely anything of 

 importance to be found ; in May the vegetation may be more inter- 

 esting. In that part which lies at the foot of the Trevenque, whose 

 immense cone rises here proudly, the Adenocarpiis decorticans is, as 

 I have said, very common ; besides this, the Jimiperus 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, Scahiosapulsatilloides ; 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., AnthylUs 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 Berheris vulgaris, var. australis, charac- 

 terizes the mountain region, and extends into the alpine region, and 

 is everywhere common, especially on arid sunny spots. 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 Inula montana ?, the beautiful Echium 

 albicans. Lag., and others, are limited to some localities. Of 

 Cryptogamia, beside some few mosses and liverworts, some Algcs 

 Olid Aspidium nevadense, Boiss., there are only lichens, apparently in 

 great quantity, especially of the genera Parmelia, Lecidea and Fi?r- 

 rucaria. 



No. V. GuEJAR 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
