both sides of the Sierra, exceedingly frequent ; Anthyllis Webbiana, 

 Hook. ; Pyrethrum radicans. Lag. ; Lepidium sty latum, Lag. ; Eryn- 

 gium glaciale, Boiss., very frequent up to the highest summits ; Silene 

 Boryi, Boiss. ; Cerastium ramosissimum, Boiss. ; Carduus carlinoides, 

 DeC. ; Herniaria alpina, L. ; 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 

 mixta. Lag. ; Linaria origanifolia, DeC, y. glareosa, Boiss. ; L. su- 

 pina, DeC., var. nevadensis, Boiss., rare; Artemisia granatensis,

 of Manzanilla ; Umbilicus sedoides, DeC. ; besides Eryngium glaciate, 

 Ptilotrichum purpureum, Pyrethrum radicans, Jasione amethystina^ 

 Sideritis scordioides, var., and Agrostis nevadensis. 



Upon the above-mentioned Borreguiles are found in particular the 

 following plants : Saxifraga stellaris, L., also frequent near the rivu- 

 lets of the upper alpine region ; Stellaria cerastioides, L. ; Campanula 

 Herminii, Lk. and Hoffmsegg. ; Pedicularis verticillata, L. ; Euphra- 

 sia minima, Schleich. ; Reseda complicata, Bory, descending into the 

 alpine valleys ; Ranunculus angustifolius, var. uniflorus, DeC. ; R, ace- 

 tosellcefolius, 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 S. Juan; Pinguicula 

 leptoceras, Rchb. ; Lotus corniculatus, 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 : Saxifraga 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 Polio de Vacares, and in the Val de Casillas ; 

 Nepeta Nepetella, L., ditto; Fij cm j9y rewaica, 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 ; Euphorbia 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
