49. BRACHYPHRAGMA Rydb. Am. Jour. Bot. 16: 204. 1929. 



Perennial herbs, with more or less pubescent foliage. Leaves odd-pinnate, with several 

 or many leaflets and more or less adnate stipules. Flowers in axillary racemes, with small 

 persistent bracts. Calyx-tube campanulate, the lobes mostly equal, subulate. Corolla purple 

 or white. Banner obovate, slightly arched, subsessile. Wings clawed, the blades lanceolate 

 or oblong, with a basal auricle on the upper side. Keel-petals shorter, clawed, the blade broadly 

 lunate, obtuse or rounded at the apex. Stamens diadelphous (9 and 1), the sheath almost 

 straight, the free portion of the filaments short, upturned. Ovary sessile or short-stipitate, 

 the style lightly curved, the stigma terminal, minute. Pod coriaceous, terete or nearly so, 

 oblong or elliptic, lance-ovoid, splitting at the apex, with a partial septum, which does not 

 reach the apex, nor the upper suture. Seeds several.
