2A3B2C2D. Pods not jointed to stipe which is mostly longer 
than the calyx, nearly straight (much arched in A. Inyo- 
ensis). 
2A3B2C2DE. Pods rather abruptly contracted at both

ably reflexed but appearing ascending. Upper

ner about 5 mm. long, oval. Calyx tube about

densely congested, prostrate, densely leaved and 
with short internodes. Peduncles stout, longer than 
the leaves. Leaflets oval-obovate 6-9 mm. long.

raised and thickened but not produced as a sharp 
edge. 
Pods smooth. i 231 Nevinii. 
Pods short-woolly. 232 Traskiae. 
2A3B2C2D2E. Pods very narrowly linear and greatly 
elongated, 4-6 cm. long and hardly 3 mm. wide or high,

215. Astragalus distortus T. & G. Fl. 1 333 (1838). Traga- 
cantha Kuntze, Tium Rydberg. 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 in the type in cross-section, with both sutures intruded 
and sulcate on both side of the pod, but sulcate most along 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- 
ture, rarely truncate at base, swollen in the middle, 2-4 cm. long,
