ear, obtuse, entire, 1-2 inches long: racemes rather few-flowered, lax in 
fruit: flowers 2-3 lines long: fruiting pedicels 4-5 lines long the slender pods 
about 14% inches long, ascending or suberect: seeds elongated, scarcely 
compressed. On clayey bluffs and banks, Oregon and Washington to 
Montana and Wyoming. 
Tribe IV. Stanleye. Pods longitudinally 2-celled dehiscent

6, well exserted ; filaments long and slender; anthers narrowly 
linear, sagittate at base curved or coiled. Stigma usually small. 
Pods slender, terete or quadrangular, often torulose, borne 1pon 
a short thick stipe. Seeds in 1 vow somewhat compressed.
