 HOSACKIA Ben th. and American authors. 



Herbaceous or suffratescent plants with pinnately one to sev- 

 eral-foliolate leaves with gland-like, rarely scarious or foliaceoiis, 

 stipules and one to several-flowered axillary peduncles, the flower 

 often subtended by a l-o-foliolate bract. Calyx 5-toothed or 

 -(deft, 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 acutely 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.
