215. Astragalus distortus T. & G. Fl. 1 333 (1838). Tra^a- 

 cantha Kuntze. Tium Rydberff. Pods from lunate and conspicuously 

 tapering at both ends to oblong-obovate, lanceolate or oblanceolate 

 and less sharply pointed, variable on the same plant, reniform to 

 didymous m the type in cross-section, with both sutures intruded 

 and sulcate on both side of the pod, but sulcate most alon? the dor- 

 sal suture and that suture variously produced but mostly ' nearly 

 touching the ventral, pod inclined to be obcompressed in the type, 

 much arched or very oblique but tip straight and symmetrical and 

 triangular to apiculate, pod often twisted and rugulose with uneven 

 sides, rather smooth and reticulated except close to the ventral su-
