190 Botanical Notices from Spain. 
distance they appear quite white, and have frequently deceived me. 
On the margin of the alpine rivulets and on moist alpine meadows 
grow Savifraga stellaris, L., Parnassia palustris, L., Euphrasia mi- 
nima, Schleich., and some liverworts ; in begs of the mountain re- 
gion Juncus bufonius, J. glaucus and a Senecio, whilst the fissures of 
the limestone rocks are filled especially by Linaria origanifolia and 
Antirrhinum molle. On the fallow fields around Trevelez I found 
here and there Jasione montana, L., a rare plant in Andalusia, and 
very frequent Carlina corymbosa, which grows high up into the al- 
pine region, as well as Polygonum Persicaria and lapathifolium. On 
walls and hedges in the environs of the village grow Senecio linifo- 
lius, L., very frequent and in full blossom, Artemisia Absinthium, L., 
Mentha rotundifolia, sylvestris and Pulegium, Brassica adpressa, Boiss., 
Crambe filiformis, Jacq., Rumex pulcher, Helichrysum serotinum, 
Boiss., Alihea officinalis, Rubus hispanicus, Pieris aquilina, Cystopteris 
Sragilis, Asplenium Trichomanes, A, Adiantum-nigrum and Ceterach 
officinarum, all which plants I have for the most part met with on 
the north side. ‘The Mulahacen yielded a somewhat richer booty ; 
I began its ascent on the 15th of September, after having in vain 
attempted to ascend it three weeks before from the north side, when, 
instead of the Mulahacen, I came upon the Cerro Alcasava, and 
found my way back only with great danger over the frightful rocks 
of the northern declivity. The ascent to the highest summit of the 
Sierra Nevada (according to the measurement of D, Simon de Roxas 
Clemente equal to 42593 varas castellanas, or 12,779 feet, which 
appears to be somewhat exaggerated) is not at all dangerous starting 
from Trevelez, at least in fine weather, which I was so fortunate as 
to have. After ascending for six hours, I came at noon to a pretty 
steep and pathless acclivity, on the highest rocks of the summit, and 
obtained such a magnificent view over a great portion of Spain, 
bounded by the sea and the coast of Africa, as is seldom presented. 
With the exception of some lichens, there is only found between the 
loose masses of rock of the summit, which consist of mica, contain- 
ing an endless number of garnets, the Artemisia granatensis, with 
the pretty Evigeron frigidum, Boiss., which is distributed over the 
whole of the upper snow region, but everywhere only sparingly, in 
company with Viola nevadensis, Galium pyrenaicum and Ptilotrichum 
purpureum. On the side opposite to the Picacho de Veleta, about 
100 feet below the summit, I found about a dozen specimens of 
Papaver pyrenaicum, Gouan., already in fruit, gathered by M. Bois- 
sier on the same spot seven years ago, without doubt the rarest plant 
of the Sierra Nevada, as hitherto no other habitat is known, and 
even here it occurs very seldom. On the wet alpine meadows on 
the southern declivity of the Mulahacen and on the margins of the 
rivulets I found the dwarf Gentiana Boryi, Boiss., immersed among 
mosses, in company with G. alpina and G. Pneumonanthe, var. de- 
pressa, Boiss., Ranunculus angustifolius, DeC., and Plantago nivalis. 
On a subsequent excursion of two days, which I made on the 16th 
and 17th of September toward the Puerto del Lobo lying nearly at 
the east end of the Sierra, I found that the eastern portion of the
