 tains, Arizona. October 1, 1929. Plants with the habit and size of 

 A. Californica and shrubby. Leaves many, bluish as if glaucous

 Leaves 3-4 inches long, narrow, with 6-8 pairs of oblanceolatc, 

 rounded and apiculate and mostly folded leaflets about an inch long. 

 Racemes axillary, linear, about 4 inches long and on short peduncles, 

 many-flowered, erect. Pods somewhat reflexed on capillary pedicles 

 2-3 mm. long. Pods ashy with minute pubescence, not glandular, oval, 

 a little flattened, about 4 mm. long, triangular-apiculate with a stout 

 style about their own length, 1-seeded. There is no evidence of gland- 

 ularity in the leaves. Stems striate. Flowers absent.
