HOSACKIA Benth. and American authors. 
Herbaceous or suffrutescent plants with pinnately one to sey- 
eral-foliolate leaves with gland-like, rarely scarious or foliaceous, 
stipules and one to sey eral-flowered axillary peduncles, the flower 
often subtended by a 1-5-foliolate. bract.. Calyx 5-toothed or 
-cleft, the teeth nearly equal, usually longer than the tube. 
Petals free from the stamens, nearly equal, the upper one ovate 
or roundish, lateral ones obovate or oblong, keel ‘somewhat in- 
curved, obtuse or ‘ac utely beaked. Stamens diadelphous; the 
alternate filaments dilated or thickened under the anthers. Pods 
linear, compressed or terete, straight or arcuate, sessile, dehis- 
cent or indehiscent, 1-several- seeded, with spongy partitions be- 
tween the seeds. Seeds variously rounded or elongated, some- 
times quadrate. smooth, tuberculate or rugose.
