yi to x /-2 the width of pod; stipe stout, as long as the calyx 

 and not jointed to the pod. This is nearest to A. Panamintensis 

 Sheldon Bot. Death Valley Exp. 87 and is allied to A. obscurus 

 Watson Bot. King, v 69. It differs from A. Panamintensis in 

 the shape and number of the leaflets, the pubescence, in the 

 calyx not being narrowed below, in the larger pods, in the white 

 not purple flowers, and in the habitat which is in the high moun- 

 tains of Oregon. This has been called A. Bourgovii by many 

 and is so referred in the Gray Herberim but not by Gray. Trout 

 Creek, Blue Mts. Oregon, May 25th, 1885, Howell. Union Co, 

 Oregon, May to June, Cusick. Also by Leiberg in the same sit- 

 uations in 1896. First collected by Barthoff at Harney, Oregon, 

 April to May, 1875. 



Astragalus oqcalycis n.sp. Habit of A. pectinatus Douglas. 

 Erect, perennial, stems flexuous, two feet high; leaves thick, as- 

 cending 4 inches long, with rachis 3 inches or less, and the pet- 

 iole about an inch long, rachis tapering and channeled; stip- 

 ules hyaline, deltoid-triangular, connate below, 2 to 3 lines long, 

 adnate; leaflets 8 pairs, opposite, linear-elliptical, acute at both 

 ends, long-petiolulate, puberident below, glabrous above, 1% 

 inches long, 3 to 6 lines apart, nodes 1 to 1^ inches apart; pe- 

 duncles 3 inches long, stout; flowers densely spicate in a head 2 

 inches long, nearly sessile, reflexed somewhat; hyaline bracts 3 

 to 4 lines long; calyx greatly inflated, 4 lines long, 3 lines wide, 

 hyaline, obliquely inserted, base straight, upper side arched es- 

 pecially near the base, teeth triangular and a line long; the pods 

 are those of A. Haydenianus, very shortly stipitate, obcompressed* 

 oval, 3 lines long, 1^2 lines wide, ventral suture thick and raised, 

 pod finely cross-striate, not at all exserted from the calyx, gla- 

 brous; corolla white, 3 lines longer than the calyx; banner oval, 

 thick at base, arched to 45 degrees or more in a gentle arc, 

 erect part a little over a line high, sides reflexed above; wings 

 oblanceolate. nearly straight, nearly as long as banner, about a 

 line longer than the obtuse, short, purple-tipped keel; calyx 

 villous with white hairs. This has in common with A. Grayi, A. 

 grallator, A. Palliseri and A. hyalinus the appearance of being a 

 sport. A. grallator *»<J A. Palliseri have been proven to be
