petiolulate, sub-alternate, emarginate, thickish, 3-4 lines long leaf- 
lets: whole plant nearly glabrous; pubescence fixed by the base, 
of short, appressed hairs; peduncles axillary throughout, %4-1 
inch long with rachis the same, racemosely 6-8 flowered; bracts 
minute, triangular; pedicels slender, 1 line long; flowers white, 3 
lines long, arched, reflexed; calyx tube campanulate, 1 line long, 
not oblique, narrowed below, teeth triangular, a little shorter and 
not arched; banner purple-veined, 2 lines long,oval, abruptly arched 
to go° at calyx tips, sides reflexed, % line wide; wings oblong» 
ascending, 1 line longer than keel; keel a little exceeding the 
calyx teeth, rounded, obtuse, short, incurved, tip erect and 
straight; pods arcuate, oblanceolate, triangular-acute, when 
young laterally compressed, when mature inflated and cross sec- 
tion oval-reniform, sulcate dorsally and septum a little intruded, 
not nearly reaching the ventral suture, 3-3% lines high and 
wide, sessile, nearly glabrous, papery, horizontal, with the calyx 
vental reflexed, not sulcate ventrally, nor ventral suture raised} 
stipules triangular, adnate, not connate, small, green. Distri- 
buted as A. drepanolobus. This has the habit of 4. drepanolobus 
and the inflated pod of A. Geyeri. Dedicated to Prof. Craig, in 
whose herbarium it was found. 
Astragalus Cusickii Gray. This interesting species was first 
discovered many years ago by Mr. Cleburne, a part of his 
original material being in my herbarium, but it was only a few 
years ago that it came into my possession. Cleburne’s speci- 
mens were gathered at the entrance of the great Snake river 
cafion, just opposite Huntington, Oregon, in Idaho. Cusick’s 
specimens were gathered also in Idaho and in the same cafion, 
but further north, near the town of Ruthberg. Last year the 
writer found the species growing abundantly at the type locality, 
and also at Goff, Idaho, near the mouth of the Little Salmon 
river. This season I also found it in full flower and fruit at Cle- 
burne’s locality, and had a chance to study it growing. It 
always grows on steep and gravelly hillsides in the Purshia 
(oak) belt. It has the habit of A. filzpes Gray and the flowers 
‘are scarcely distinguishable from that species, but the ballon- 
shaped pods show that it is closely related to 4. Hookerianus.
