short claw 1mm. long and as wide at top, pointed at base; wings 
7mm. long, including the slender claw of 1.5mm., 3mm. wide 
above the middle, 1.5mm. at the base, where they are prolonged 
into a short acumination; keel glabrous, 2 mm. deep at the mid- 
dle, the ventral side nearly straight, the dorsal strongly curved, 
apex with a short blunt point: fruit immature. 
The type, in the herbarium of A. A. Heller, is Heller 5745, 
collected near Burke’s Sanitarium, Sonoma county, California, 
June 24, 1902.

“30. HY. mollis (Nutt.! mss.): “hirsute with spreading hairs: 
erect branching from the base; leaflets oblong and cuneite-ob- 
long, obtuse; peduncles longer than the leaves; bract of a single 
leaflet; calyx as long as the corolla; legume almost flat, glab- 
Tous. 
“Gravel bars and sandy shores of the Wahlamet, near the 
Falls. June.—Abouta span high, moderately branching. Bracts

H. floribunda.”

It agrees in habit and pubescence. Some of the terminal leaflets 
are obtuse, but as a whole they are at least acutish, some de- 
cidedly acute. The flowers are few, scattered froin the middle 
part of the stem up, pink or salmon, apparently without dark 
veins, 7mm. long, about 4mm. deep: calyx 5mm. long, llobes 
subulate-acuminate, over 3mm. long, ciliate: banner suborbicu- 
Jar when spread out, the blade 5inm. broad and but little longer, 
the narrow claw 1.5mm. long, 0.5mm. wide, but little narrowed 
at base; blade of wings 4mm. long, 2mm. wide, auricled at 
base; keel 6mm. long, 1.5mm. deep at the middle, the ventral
