Cal. tubular, permanent, divided halfway down into 5 awl- 

 shaped, straight segments. Cor. of 5 petals ; standard 

 ovate-oblong, keeled at the back, slightly cloven, reflexed 

 at the sides ; wings oblong, straight, narrower than the 

 other petals ; keel of 2 united petals with separate claws, 

 compressed almost flat, very abrupt and straight, almost 

 rectangular, in front. Filam. 10; 9 in one flattish tube, 

 open above ; the tenth awl-shaped, distinct, usually 

 shorter; all capillary, and bent upwards, at the extremity. 

 Anth. roundish. Germ, ovate, or oblong, compressed. 

 Style awl-shaped, curved upwards. Stigmp. simple, acute, 

 naked. Legume of one or more roundish, compressed, 

 bivalve but close joints, each containing a solitary, kid- 

 ney-shaped seed. 



A very numerous, herbaceous or shrubby genus, w'ith pin- 

 nate, ternate, or simple leaves; copious, handsome, clus- 

 tered, crimson or purplish^ow^r5; ?iud seed-vessels so va- 

 rious, that an over-curious fabricator of genera might 

 here find ample employment, though not to any good 

 purpose. Stylosanthes of Swartz, and Hallia of Thun- 

 berg, have indeed been well removed from the original 

 Hedysarum*
