cel, or rarely shortly pedunculate: leaflets mostly linear, palmate upon a. 
very short petiole or sessile—New Mexico and Arizona; Willow Springs, 
Loew (1114), and White Mountains, Arizona, Loew (1113), and Fort Win- 
gate, N. Mex., Rothrock (152). . 
Hosacxra Pursniana, Benth.—Annual, usually a foot high or more, 
and more or less silky-villous: leaflets 1 to 5, ovate to narrowly lanceolate, 
2 to 9 lines long; stipules gland-like: flowers small, ‘yellow, on pedun- 
_ cles exceeding the leaves, bracteate with a single leaflet: calyx-teeth linear, 
“much exceeding the tube, about equalling the corolla: pod linear, straight, 
smooth, an inch long, 5-7-seeded.—Frequent from the Mississippi to the 
Pacific; Nevada, 1871, and Camp Grant, Ariz. (368). 
TEPHROSIA LEIOcaRPa, Gray (Pl. Wright. ii, 36).—Perennial, erect, 
rather stout, a foot high or more, with a fine, appressed, silky pubescence : 
leaflets 6 to 10 pairs, linear-oblong, obtuse, mucronate, smooth above, 
shortly petiolulate, about an inch long: peduncles terminal and axillary, 
scarcely exceeding the leaves, rather few-flowered: calyx-lobes subulate, as 
long as the tube; petals large, purple, 9 lines long: pods linear, straight, 
glabrous, two inches long by three lines wide, sessile, about 10-seeded.— 
Arizona, Sanoita Valley, Rothrock (685), near the original locality, where 
only it had been collected by Mr. Wright—Very near 7. onobrychoides, 
Nutt. Differing in its short peduncles and smooth pods. 
TepHrosta LeucantHa, H. B. K. (Nov. Gen. vi, 460, t. 577).—Peren- 
nial, erect or ascending, rather stout, about a foot high, appressed-pubescent 
avd somewhat rusty silky-villous throughout, the hairs upon the petioles 
spreading: leaflets 5 to 12 pairs, oblong, rounded at each end, mucronate, an _ 
inch long: raceme terminal, short and shortly peduncled: flowers yellow, 6 | 
or 7 lines long, exceeding the erect slender pedicels : calyx very villous, the 
slender lower teeth longer than the tube: style pubescent: pods narrowly 
linear, straight, spreading, densely rusty pubescent with short spreading 
hairs——Southern Arizona, apparently identical with the typical form of 
Central Mexico; in Sanoita Valley, Rothrock (625). 
Tepnrosta TeNeLLA, Gray (Pl. Wright. ii, 36)—Annual, erect, very
