hirsute-strigose triangular stipules; leaves pinnate with 5 approxi- 

 mate leaflets ; these 3-4 mm. long, lanceolate, strongly condupli- 

 cate, grayish hirsute, spine-tipped ; racemes 1-2-flowered, very 

 short-peduncled in the axils of the leaves ; calyx-tube scarcely 2 

 mm. long, grayish strigose ; teeth subulate, about 1 mm. long; 

 corolla ochroleucous, about 4 mm. long. 



A species related to and confounded with H. tegetarius 

 {Astragalus tcgetarius S. Wats.), but the latter is a larger plant, has 

 long-peduncled raceme exceeding the leaves, and longer calyx 

 teeth, which about equal the tube in length.

Homalobus Clementis sp. nov. 



Perennial, slightly branched, erect or ascending ; stem glab- 

 rate or slightly strigose, about 2 dm. high ; stipules broadly 

 triangular, strigose, abruptly acuminate, more or less united across 

 the back ; leaves 5-7 cm. long, with 11 -21 leaflets; these oblong 

 or lanceolate, acute, 7-12 mm. long, glabrous above and spar- 

 ingly strigose beneath; inflorescence 7-10 cm. long, 8-12-flow- 

 ered ; bracts lanceolate, small ; flowers very short-pediceled ; 

 calyx-tube campanulate, about 3 mm. long, strigose with black 

 hairs, teeth lanceolate-subulate, about half as long ; corolla bluish- 

 purple, about 8 mm. long ; pod oblong, latterally compressed, 

 sessile, about I cm. long, 3-4 mm. wide, black-hairy with very 

 short hairs ; both sutures prominent, the upper almost straight. 



This species is perhaps closest related to Homalobus winga- 

 tensis (A. wingatensis) ; but that species is grayish canescent and 

 has a glabrous pod. H. Clementis grows at an altitude of 2,500- 

 3,000 m.

Homalobus decurrens sp. nov. 



Perennial with a rootstock, somewhat cespitose ; stems erect, 

 3—4 dm. high, slightly strigose and angled, stipules lanceolate, 

 free, about 5 mm. long, strigose ; leaves 1 — 1.5 dm. long with 11 — 

 1 5 leaflets ; these 2-4 cm. long, linear-oblong to oblanceolate, spar- 

 ingly strigose or glabrate above ; the terminal one usually larger, 

 more or less decurrent on the rachis and without a definite node ; 

 racemes slender, 1 — 1.5 dm. long, lax, 5— 10-flowered ; bracts subu- 

 late; calyx-tube campanulate, about 2.5 mm. long, more or less
