 wide ; herbage pubescent with long silky wool ; peduncles short, few-flowered, not exceeding the 

 leaves; calyx-tube 4 lines long, the teeth 1^2 to 2 lines long; pods strongly arcuate, somewhat

 longirostrata.) — Scott River Valley, Siskiyou Co., T. H. Gilbert (type). 



Var. longilobus Jones. Peduncles usually exceeding the leaves ; calyx-teeth sometimes 

 elongate ; pods somewhat obcompressed, often strongly arcuate, acutely long-beaked, 7 to 9 (or 

 15) lines long; beak straightish, strongly inflexed, % to % as long as the body. — Ranges near

Var. funereus Jepson comb. n. Similar in habit to and doubtless belonging to the A. 

 purshii group and most closely allied to var. longilobus; flowers 12 to 13 lines long; calyx con- 

 spicuously black-hairy, often much inflated, the inflation due to the rapid growth of the young 

 pod; corolla-banner oblong, making a wide angle with the wings and keel; pods about 2 inches 

 long (ace. Jones) ; beak stout, acuminate, 4 lines long. — Western Nevada. Attributed to Cali- 

 fornia but we have seen no spms. from the state. 



Var. ordensis Jepson comb. n. Herbage loosely white-woolly; leaves 2% to ZV2 inches long; 

 leaflets oblong or obovate, 4 to 6 lines long; peduncles slightly exceeding the leaves; flowers 

 purple, 7 to 9 lines long; calyx black-hairy; pods oblong, somewhat obcompressed, slightly to 

 strongly arcuate, nearly 2-celled by the intrusion of the dorsal suture. — Desert ranges, 5100 to 

 6100 feet: Mohave Desert (Granite Well, Johnston) ; Inyo Co. (Millspaugh, Argus Mts., Hall 4r 

 Chandler 7076; Hanaupah Canon, Panamint Range, Jepson 6995).
