A. Orcuttianus var. Gregorianus n. var. This differs from 
the type in the larger flowers, peduncles with floral rachis about 
1° long, leaflets obovate to obcordate. It simulates A. eremiti- 
cus, but the pods are much narrower. San Gregorio, Colorado 
Desert, California.

A. lentiginosus var. Idriensis nu. var. This very remarkable

sparsely puberulent with white hairs, a trifle inflated, deeply 
suleate dorsally to 14” deep at base, not suleate at tip, 2-celled 
except at tip, arcuate, a trifle narrowed below, shortly acumi- 
nate with pungent tip, ventral suture raised and wing-like in 
the middle, somewhat mottled, about 6” long, tip erect, cross-sec- 
tion V-shaped; flowers 4’’ long with slightly exserted claws, not 
arched, reflexed in fruit; banner elliptical, abruptly arched to 
nearly erect 1” beyond the calyx tips, erect part 2” long and the
