46. ATELOPHRAGMA Rydb. Bull. Torrey Club 32; 660. 1905. 



Caulescent leafy perennials with rootstocks. Leaves odd-pinnate, usually with many 

 entire leaflets; stipules nearly free both from each other and the petiole. Flowers in spike-like 

 axillary racemes. Calyx-tube campanulate, the lobes 5, slender. Corolla purple or white, 

 middle-sized. Banner obovate, almost clawless. Wings and keel-petals clawed, the blades of 

 the former obliquely obovate or oblong, somewhat falcate, with a rather small basal auricle, 

 those of the latter more or less lunate. Stamens diadelphous (9 and 1), the sheath straight, 

 the free part of the filaments curved upwards. Ovary stipitate, straight, the style glabrous, 

 curved upwards, the stigma minute, terminal. Pod stipitate, or rarely subsessile, mem- 

 branous or papery, the body elongate, laterally flattened or terete, more or less inflated, 

 rounded, oval or somewhat cordate in cross-section, abruptly acute, the lower suture inflexed, 

 the lower edge of the valves folded and forming a partial partition or septum. Seeds ob- 

 liquely rounded-reniform.
