Some, however, agree well with Lapland 8p(M-imens of D. nivalis^ Lilj., (refer- 
red to this species,) from Anderson, in Herb. Gray. All have glabrous iialvcd 
scapes and siiicles, with small obovate pubescent leaves ; otherwise they may 
be thus divided : (a) with very slender 1-3-flowered scapes, 2' long ; flowers 
small, petals half longer than the calyx ; silicle linear-oblong, (3-4" long,) with 
a short style ; (h) with shorter scape, and style none ; (c) with ovate siiicles, 
acuminate with a longer (J") style, (r/) and {h) are from the same locality 
in the Uinta Mountains ; 12,000 feet altitu.de August ; (c) from the East 
Humboldt Mountains, Nevada ; 10,000 feet altitude ; September. (90.) 
Deaba Douglasii, Gray. Proc. Atner. Acad. 7. 328. Caudex with 
numerous short stems ; scapes naked, corynibosely many-flowered ; leaves all 
rosidate, subcartilaginous, nearly veinless, entire, glabrous or some^\'hat hirsute 
(as also the scape) with simple hairs, his^^idly cihate, the lowest ovate, the 
upper ones obovate or spatulate •, flowers rather large, white, with oval 
glabrous sepals ; siiicles ovate, puberulent, beaked with the slender style ; 
cells 2-OYuled near the summit. — A low cyespitosc perennial ; scapes an inch 
ill height. Collected by Douglas in Northern California or Oregon, and by 
Anderson in the Sierras south of Carson City. Mount Davidson, Nevada ; 
6,000 feet aUitude : April, in flower only. (91.) 
Draba aurea, Vahl. Pubescent ; stem erect, leafy; leaves lanceolate or 
ovate-lanceolate, acute, entire or toothed ; corymbs terminal and axiUarv ; 
sHicles oldong-lanceolate, pu])escent, exceeding the pedicels ; petals (yellow, 
(»r sometimes white) emarginatc ; style ratlier short. — Biennial or perennial ; 
stonis few iti young plants, becoming many. The specimens have simple 
nuM'UH's, n stMulding those collected in Colorado and by Bourgeau. Found 
in the Ivocky Mountains, from New^ Mexico to British America. Uinta 
Mountains, Ulah; 8-11,000 feet altitude ; August. (92.) 
Draba nemorosa, L. In the Bocky ^Mountains, from Colorado to the 
xVrctic Circle and tlu^ northwest coast. Frequent in the Wahsatcli Moun- 
tains, Utah ; 4,500-8,500 feet altitude ; May-July. (93.) 
Yar. LUTEA, Gray. {D. hitca, DC.) Often with the stem nearly or quite 
leafless, and tlie petals sometimes pinkish-white; the sepals are sparsely 
.hirsute; the j^edicels scarcely exceed or are even sliortcr than the siiicles. 
Similar specimens collected in Colorado have been considered D. cmssifolia, 
Grab., but it is evidently a ibrm of the last— more alpine. In the East Hum-
