the Arctic Coast to Beliring Strait ; also collected by Parry in Colorado, 
and by Brewer in the Sierra Nevada. Numerous specimens were collected 
in Nevada and Utah, varying much, but belonging to one species. Those 
distributed under this number arc 3-4' high, with the large flowers and fruit 
in a loose raceme ; leaves spatulatc or obovate, nearly veinless, stellately pu- 
bescent; scape nearly glabrous; pods* glabrous or pubescent. East Hum- 
boldt Mountains, Nevada; 8-9,000 feet altitude; July. (84.) 
Var. Somewhat more densely matted, and crowded with the leaves of 
previous seasons ; 2-4' high ; leaves linear-lanceolate, with a more or less 
prominent mid-vein; pubescence occasionally wanting. East Humboldt 
Mountains, Nevada; 8-10,000 feet altitude; July, August. (85.) 
Var. {=D. glacialis, Adams.) A dwarf and more alpine form, still more 
compact, and the scapes but an inch high, 1-several-flowered ; leaves densely 
crowded, mure rigid and strongly midveiiied, (h-nsoly pubescent or nearly 
glabrous, not ciliate. Lyall collected similar specimens on the northwestern 
boundary, and Brewer in California. Clover Mountains, Nevada, and the 
Uintas; 10-12,000 feet altitude ; August, September. (86.) 
Var. (near D. glacialis, Var. r, Hook.) Very dwarf and matted ; scapes, 
pedicels, and silicles hirsute-pubescent, while the rigid linear keeled leaves 
are strongly cihate, but otherw^ise glabrous. Similar to 2716 Brewer. East 
Humboldt Mountains, Nevada ; 10,000 feet altitude ; August. (87.) 
Var. (=i>. algida, Adams.) Dwarf and matted ; scape very short, 1-3- 
flowered, and with the silicles glabrous; leaves ovate, glabrous, cilialc, less 
rigid, and scarcely nerved. Resembles specimens of Bongard frmn Altai, 
and of Hooker and Thompson from Tibet. East Humboldt :\I()untains, 
Nevada, and Uinta Mountains, Utah; 10-12,000 feet altitude. August. (88.) 
Draba stellata, Jacq. Perennial ; scape with a single leaf, pubescent ; 
leaves oblong-oval, tomenfose with a short stellate pubescence; [K'dicels

entire, canescent, with a soft stellate pubescence; silicles oblong-lanceolate, 
glabrous; flowers white. — Labrador and Arctic America. Considered by 
Hooker distinct from the last. Tlu; specimens vary considerably from the
