Stout erect perennials, with a woody base. Leaves odd-pinnate, usually with many 

 leaflets (in the type unifoliolate) and broad free stipules. Flowers in long-peduncled axillary 

 racemes, nearly sessile. Calyx-tube campanulate, with rather long calyx-teeth. Corolla 

 ochroleucous or with purple- tipped keel. Banner obovate, clawless, moderately arcuate. 

 Wings with an oblanceolate blade and a large basal auricle. Keel-petals with a short claw 

 and a lunate blade. Stamens diadelphous (9 and 1), the sheath straight. Ovary many- 

 ovuled, the style glabrous, curved upwards, the stigma minute. Pod leathery, inflated, 

 sessile, terete in cross-section, the lower suture with a narrow partial septum.

Pod oblong or lance-oblong in outline, less than 1 cm. in diameter. 

 Leaflets strigose beneath; pod abruptly contracted at the base, 

 gradually acute at the apex, short-stipitate; calyx-lobes spreading 

 in age; pod erect. 2. J. Patter soni.
