Leafy-stemmed perennials. Leaves odd-pinnate, with mostly distinct stipules. Flowers 

 in axillary racemes on rather long peduncles. Calyx-tube eampanulate, the teeth mostly 

 subulate. Corolla ochroleucous or rarely purplish. Banner obovate, clawless. Wings 

 clawed, the blade obliquely oblanceolate, with a small basal auricle. Keel-petals with the 

 claw longer than the blade, which is broadly lunate. Stamens diadelphous (9 and 1), the 

 sheath straight, the free portion of the filaments upcurved; ovary stipitate or sessile, many- 

 ovuled, the style upcurved, the stigma minute. Pod leathery, stipitate or sessile, elongate, 

 terete or compressed, the lower suture sometimes sulcate, the valves incurved and adnate 

 forming a partial septum, extending to near the tip. Seeds obliquely round-reniform. 



Type species, Astragalus sulcatus L. 



Pod pendulous, the body linear or lance-linear in outline. 



Pod distinctly stipitate. the stipe mostly longer than the calyx; upper suture 

 acute, the lower decidedly sulcate. 

 Corolla 15-20 mm. long; banner moderately arched; lower edge of the 



keel-petals abruptly arched upward near the apex; plant stout. 1. Racemosa. 



Corolla 7-12 mm. long; banner more strongly arched; lower edge of the 

 keel-petals more uniformly arched throughout the blade; plant slender, 

 less than 5 dm. high; pod usually falcately curved upward. 2. Misella. 



Pod very short-stipitate or subsessile; upper suture more rounded. 



Corolla less than 1 cm. long; plant slender, less than 4 dm. high; pod 



straight or curved downward. 4. AtraTa.
