obtuse, the lateral ones linear-subulate and obtuse, the upper ones trian- 

 gularly subulate and acutish ; sinuses narrow, but the upper one very broad 

 and deeper with a rounded bottom. Corolla much exserted, glabrous, 

 deciduous, white, but .purpurascent towards the apex of carinte ; vexillum 

 horizontal below and ascending above, obovato-elliptical or elliptical, grad- 

 ually cunea to-attenuated towards the base, emarginate, about 14 mm. long, 

 7 mm. wide ; aire somewhat shorter than vexillum, unguiculate, narrowly 

 oblong, obtuse, auriculate with a descending obovate rounded-tipped lobe at 

 the base, about 3^ mm. broad, unguis linear, shorter than the lamina, 

 about 4J mm. long ; carinre connate with the inner edges, obviously shorter 

 than vexillum, horizontal, obliquely obovato-elliptical, obtuse, auriculato-sagit- 

 tate at the base, about 9 mm. long, about 3 mm. broad, the unguis very 

 slightly shorter than the lamina. Stamens nearly equal to the carina, 

 glabrous, the connate portion narrow, the free portion unequal in length ; 

 anther elliptical, yellow. Ovary very slightly exceeding the calyx, linear- 

 fusiform, thinly adpressed-puberulent, very shortly stipitate (the stipe about 

 1 mm. long and glabrous), about 4 mm. long including the pedicel, l-celled, 

 provided with a narrow rudimentary dissepiment on the dorsal suture inter- 

 nally ; ovules about 4-6, reniform ; style curved upwards, linear, attenuated 

 above, glabrous, longer than the ovary, with a capitate glabrous terminal 

 stigma. Legume very shortly stipitate, lunato-oblong, acute at apex, thinly 

 dispersed with adpressed nigrescent hairs, firmly membranaceous, with deli- 

 cately elevated and very loose transverse veins, about 13 mm. long, 6 mm. 

 broad, the dorsal side very deeply silicate by the introflexion, l-celled and 

 with double thin narrow dissepimental lamellfe at the dorsal suture within.
