182 RYDBERG: NOTES ON FABACEAE—I 
specimen in the Gray Herbarium has narrowly linear leaflets 
and the stipe of even very immature pods is quite as long as the 
calyx.’’ These statements do fit Nuttall’s specimens of “H. 
nigrescens”’ in the Torrey Herbarium but not his description of 
H. dispar. The specimens in question were collected on the 
Missouri, but I do not know the date; there is no evidence that 
they came from Fort Mandan. 
9g. HOMALoBUs sTIPITATUS Rydb. Although H. tenellus is 
much more common than H. dispar, the two species have nearly 
the same range; H. stipitatus is confined to the northeastern 
part of thisrange. All the specimens in the New York Botanical 
Garden Herbarium are cited under the original description and 
need not be repeated here. 
10. HOMALOBUS sTRIGULOSUS Rydb. Macbride has reduced 
this to Astragalus tenellus forma strigulosus. An additional 
specimen is here recorded :-— 
UtaH: Jugtown, Jenes 5400. 
11. Homalobus Standleyi sp. nov. 
Astragalus tenellus var. Clementis Macbride, Contr. Gray Herb. 
IT. 65: 35 (in part). 1922. 
A perennial, with a caespitose caudex; stems 2-3 dm. high, 
sparingly strigose; stipules deltoid, about 2 mm. long, connate; 
leaves 3-5 cm. long; leaflets nine to fifteen, elliptic or oblong, 
5~10 mm. long, 2-3 mm. wide, glabrous above, strigose beneath; 
acemes lax, 4-7 cm. long, including the short peduncle; bracts 
lance-subulate, 1-2 mm. long; calyx strigose, the tu . 
ong, the teeth subulate, fully 1 mm. long; corolla white or 
tinged with purple, the keel purple-tipped; banner 6 mm. long, 
obovate, slightly retuse; wings 5 mm. long; keel-petals 5 mm. 
long, with a rounded apex; pod about 1 cm. lon mm. broad, 
strigose, elliptic-oblong, acute at each end, short-stipitate, the 
stipe shorter than the calyx-tube. 
TYPE collected at Ponchuelo Creek, New Mexico, July 4, 
1908, Standley 4181 (herkarium of the New York Botanical 
Garden). 
This is closely related to H. strigulosus but differs in the 
white or purple-tinged (not ochroleucous) corolla, with a de- 
cidedly purple-tipped keel, and in the narrower pods with much 
shorter stipes. Macbride thought that this belonged to H. 
Clementis Rydb. and, on account of the similarity of the pod 
.
