20 PITTONIA. 
double hairs; petals large, cream-color, obtuse, entire: ped- 
icels much shorter than the pods and distinctly villous 
throughout; pods linear, acute, } to $ inch long, slightly 
contorted, rough-puberulent, tipped with a short and slender 
style. 
From the same region as the last, and by the same col- 
lectors; and inexcusably mistaken for D. streplocarpa, a plant 
whose best character is that of being villous and not at all 
stellate-pubescent. 'lhe most robust specimens are those 
flowering and fruiting luxuriantly as biennials, or at least, 
the second year from the seed; but others show a perennial 
duration of the root. 
DRABA DEFLEXA. Stein stout, erect, 3 or 4 inches high, 
racemose almost from the base: leaves mostly in a dense 
rosulate basal tuft, oblong-lanceolate, entire or sparingly 
toothed, nearly glabrous superficially, but the margin hir- 
sute-ciliate: calyx glabrous, the thin sepals tinged with 
purple: petals white, showy: pedicels widely spreading, in 
fruit deflected, much exceeding the pods in length, these 
elliptic-oblong, } or $ inch long, glabrous, the stigma small 
and sessile. 
Camp Stambaugh, Wyoming, collected in 1878, by Dr. 
Maghee; specimen preserved in the U.S. Herbarium, with- 
out a name. 
THELYPODIUM CRENATUM. Perennial, the stout stems sev- 
eral from a branching caudex and 3 feet high: herbage 
green, wholly devoid of bloom: lowest leaves oblong-oblan- 
ceolate, obtuse, tapering to a rather long petiole, strongly 
erenate or crenate-serrate ; cauline leaves reduced and scat- 
tered, lanceolate, sessile, subentire: racemes short, corym- 
bose-panicled: corollas white, the petals small and obtuse: 
pod not seen. 
Mancos sage plains, southern Colorado, Baker, Earle and 
Tracy (n. 394); distributed as T. integrifolium, but certainly 
distinct by its perennial roots, thin crenate leaves, and herb- 
age not in the least glaucous.
