at the apex, thick, sparingly strigose, soon glabrate, 5-10 mm. 
long; peduncles 4-7 cm. long; raceme short, 1-2 cm. long, in 
fruit 3-6 cm. long, 3—15-flowered ; calyx black-hairy ; tube 2-2.5 
mm. long; teeth subulate, 1-2 mm. long; corolla ochroleucous ; 
banner 6—7 mm. long ; wings and keel 5 mm. long; pod scarcely 
stipitate, about 2 cm. long, 4 mm. broad, oblong, tapering at both 
ends, slightly arcuate, sulcate on the lower suture except at the 
ends, acute on the upper suture, mottled with purplish-brown and 
minutely strigose. 
This is perhaps most nearly related ‘to T. sparsifiorum (A. 
Gray) Rydb., but is a much larger and coarser plant. The latter 
species has usually smaller leaves, smaller corolla, white and 
tinged with violet, strongly oblique calyx and pods of about half 
the length, more curved and more distinctly stipitate.

Hamosa atratiformis 
Perennial ; stem 2-3 dm. high, erect, branched, strigose ; stip- 
ules triangular, strigose, 1-2 mm. long; leaves 3-5 cm. long ; 
leaflets 13-19, oblong, strigose below, glabrous above, 4-6 mm. 
long ; peduncles 5-7 cm. long: raceme lax, 2-3 cm. long; calyx 
black-strigose ; tube about 2 mm. long; teeth subulate, I mm. 
long; corolla ochroleucous, about 7 mm. long; pod linear, 
straight, minutely strigillose. 
This is closely related to H. atrata (Astragalus atratus S. Wats. 
Bot. King Exp. 69. 1871), but differs inthe short leaves and the © 
smaller flowers, which are scarcely more than half as long as in 
that species.
