420 RYDBERG: Rocky MOUNTAIN FLORA 
Homalobus strigulosus sp. nov. 
Cespitose perennial ; stems erect or ascending, branched, 1-3 
dm. high, strigulose; stipules short, ovate ; leaves 3—4 cm. long; 
leaflets linear, acute, 8-12 mm. long, 1-2 mm. wide, thick, glabrous 
above, strigose beneath ; peduncles 1 cm. or less; raceme lax, 
1.5—3 cm. long, 4—7-flowered ; bracts minute, subulate ; calyx stri- 
gulose ; tube campanulate, 1.5 mm. long ; teeth subulate, less than 
I mm. long ; corolla ochroleucous, about 6 mm. long ; pod strigose, 
shining, stipitate ; body oblong, 7-8 mm. long, 3 mm. wide, rather 
gradually contracted into the stipe, which is about 3 mm. long. 
This is closely related to H. ¢encl/us, but differs in the smaller 
flowers and the smaller and hairy pod. It grows at an altitude 
from 1800-3000 m.

: Diholcos micranthus sp. nov. 
Somewhat cespitose perennial; stems erect or ascending, 
sparingly strigose or glabrate, 2-4 dm. high; stipules ovate, about 
5 mm. long; leaves 4-6 cm. long ; leaflets 17—25, linear or lance- 
oblong, acute at both ends, 7-20 mm. long, glabrous above, stri- 
gose beneath ; peduncles 4-7 cm. long ; racemes many-flowered, 
3-7 cm. long ; calyx strigose ; tube campanulate, slightly gibbous, 
2-2.5 mm. long; teeth subulate-filiform, 1-2 mm. long, the upper 
somewhat shorter ; corolla 6-7 mm. long, ochroleucous ; pod stri- 
gose, obsoletely if at all cross-ribbed stipe 3-4 mm. long ; body 
scarcely I cm. long, 3 mm. wide, very acute. 
This species is related to D. Hlaydenianus (A. Gray) Rydb. 
[Astragalus Haydenianus A. Gray], differing in the smaller 
flowers and fruit, the more acute leaflets, the narrower calyx-lobes, 
and especially the almost total lack of cross-ribs on the more 
acute legumes. D. micranthus was included in D. Haydenianus 
in my Flora of Colorado.
