Grand River. 
ASTRAGALUS BISULCATUS and HAYDENIANUS are two species 
that I have studied much, and have come to the conclusion that 
they are hardly distinct. The only characters that hold still are the 
light colored flowers and the slender habit as distinguishing AHay- 
denianus from disudcatus. I doubt not that these will disappear 
with further study, or rather search; until that time comes, however, 
it will be best to keep up the species. The two varieties given be- 
low will be usefuktill the species is superseded. ; 
Characters common to both dzsudcaius and Haydenianus. Plants 
perennial from a woody root, many stemmed, 2 to 3 feet high, 
branching toward the top; lower stipules connate and scarious, up- 
per broadly triangular and acute; stems, petioles and peduncles 
grooved; leaflets when fully developed nearly or quite an inch long; 
pedicels hairy, 2 lines long; calyx saccate, cleft on the upper side, 
hyaline, ochroleucous, lobes subulate, unequal; flowers with a-very 
strong snake-like odor, horizontal, reflexed or pendent in fruit; keel 
purple tipped; banner veined below; pods semi-circular in cross- 
section, deeply bisulcate on the ventral side, ventral suture prom- 
inent, pod more or less rugulose-veiny; stipe as long as the calyx; 
proper peduncles equaling the leaves; spikes elongating in fruit. 
ASTRAGALUS BISULCATUS Gray. Stout, nearly erect; leaflets 
broadly to narrowly lanceolate, obtuse, often apiculate, less than an 
inch long, 8 to 13 pairs; plant minutely pubescent even to the 
pods, but stipe glabrous and pedicels strigose; bracts 2 lines long, 
ovate-acuminate; pedicels 1 to 2 lines long; calyx 2 lines long and 
wide exclusive of the lobes, lobes 1 to 134 lines long; flowers 
purple, 6 lines long; wings ¥% line longer than the keel; banner 1 line 
longer than the keel and erect; pod narrowly oblong, quite acute at 
tip and obtuse at base, straight, 6 by 2 lines long and wide; spikes 
dense in flower; peduncles longer than the leaves. 
ASTRAGALUS HAYDENIANUS Gray. (This will become A. disz/- 
catus var. Haydenianus when merged into that species). Typical 
form. Slender stems erect; pubescence ashy; calyx-teeth much 
shorter than the tube; flowers 3 to 4 lines long, white, pods rugu- 
lose-veiny transversely; spikes elongated, virgate; pods oval, very 
obtuse at both ends, 2 to 4 seeded. This abounds in southwestern -
