both sides of the Sierra, exceedingly frequent ; Anthyllis Webbiana, 
Hook. ; Pyrethrum radicans, Lag.; Lepidium stylatum, Lag.; Eryn- 
gium glaciale, Boiss., very frequent up to the highest summits ; Silene 
Boryi, Boiss. ; Cerastium ramosissimum, Boiss.; Carduus carlinoides, 
DeC.; Herniaria alpina, lL. ; Jasione amethystina, Lag. ; Armeria au- 
stralis, Boiss., a most striking shrubby form, with stiff, almost spines- 
cent branches; Agrostis nevadensis, Boiss.—In the upper snow-region, 
9500 to 11,000 feet and above: Viola nevadensis, Boiss.; Saxifraga 
miata, Lag.; Linaria origanifolia, DeC., y. glareosa, Boiss.; L. su- 
pina, DeC., var. nevadensis, Boiss., rare; Artemisia granatensis, 
Boiss., known and celebrated as a popular medicine under the name 
of Manzanilla; Umbilicus sedoides, DeC.; besides Eryngium glaciale, 
Ptilotrichum purpureum, Pyrethrum radicans, Jasione amethystina, 
Sideritis scordioides, var., and Agrostis nevadensis. 
Upon the above-mentioned Borreguiles are found in particular the 
following plants: Savifraga stellaris, L., also frequent near the rivu- 
lets of the upper alpine region; Stel/aria cerastioides, L.. ; Campanula 
Herminii, Lk. and Hoffmsegg. ; Pedicularis verticillata, L.; EHuphra- 
sia minima, Schleich.; Reseda complicata, Bory, descending into the 
alpine valleys ; Ranunculus angustifolius, var. uniflorus, DeC.; R. ace- 
tosellefolius, Boiss.; Veronica alpina, L.; Gentiana verna, L., also 
frequent on the banks of the alpine lakes; G. Pneumonanthe, var. 
depressa, Boiss., especially on the Borreguil de 8. Juan; Pinguicula 
leptoceras, Rehb.; Lotus corniculaius, var. glacialis, Boiss. (very dif- 
ferent from the typical form!) ; Sempervivum tectorum, L.?; Meum 
athamanticum, L.; Epilobium origanifolium, Lam. 
The following plants appear to be more limited to certain locali- 
ties of the snow-region, but are there frequent : Sawifraga oppositi- 
folia, L., which I met with most beautiful on the frightful precipice 
on the northern declivity of the Mulehacen, called the Val de Casil- 
las; Butinia bunioides, Boiss.,in rocky clefts near the Laguna de Dilar ; 
Senecio quinqueradiatus, Boiss., on the way to the perpendicular 
groups of rocks called the Pollo de Vacares, and in the Val de Casillas ; 
Nepeta Nepetella, L., ditto; Vicia pyrenaica, Pourr., very sparingly 
in the Val de Casillas and in the upper part of the Barranco de Guel- 
non, &c. 
In the highest part of the great valleys stretching into the snow- 
region the following are very frequent: Parnassia palustris, L., in 
many places very small; Kuphorbia Esula, L.; Cirsium acaule, var. 
gregarium, Boiss. ; Carum verticillatum, Koch ; Aconitum Lycoctonum, 
L., and A. Napellus, L. Among the rarest plants of the snow- 
region are the Potentilla nevadensis, Boiss., which I have hitherto 
found only in small quantities on the Borreguil of S. Juan, and 
Linaria glacialis, Boiss., a small grayish-green and very large-flowered 
species, of which I have only met with three specimens in the highest 
snow-region. From the valleys of the upper mountain region,—for 
example, from the banks of the Monachil at S. Geronimo up to the 
snow-region,—the Digitalis purpurea, L., is found frequent, which at 
a height of from 8000 to 9000 feet takes a somewhat different habi- 
tus, but seems to me not sufficiently to differ from the typical form
