186 RYDBERG: NOTES ON FABACEAE—I 
H. miser (Dougl.) Rydb. should be withdrawn, at least 
provisionally. My conception of it was partly based on 
Gray's interpretation of the species, when he included under it 
Lyall 7, a specimen in flower only. Jones and Piper have referred 
this specimen to Astragalus microcystis A. Gray, a species of 
Phaca. 1 do not feel certain that their identification is correct 
or that Lyall’s specimen really represents Astragalus miser 
Dougl. Since Gray placed the species among the Homalobi 
and since I at that time identified certain slender specimens 
in fruit with Lyall’s plant, I admitted H. miser as valid. I now 
think that the true A. miser is still to be identified. 
C. BouRGOVIANI 
This group bears the name of Debiles in my Flora of the 
Rocky Mountains, It is desirable to change the name, however, 
since Astragalus debilis (Nutt.) A. Gray, as will be shown below, 
is an imperfectly known species. 
19. HomaLosus Bourcovi (A. Gray) Rydb. The habit 
and the black-hairy calyx and pod make this plant resemble a 
good deal Astragalus alpinus L. and Phaca elegans Hook., both 
now belonging to other genera. Except for the somewhat 
ridged valves of the pod the plant is a true Homalobus. In 
the alpine regions of the Canadian Rockies there grows a low, 
almost acaulescent form, with minute leaflets. This looks very 
unlike the ordinary form, but all grades between the two ex- 
tremes are found. 
20. Homalobus retusus sp. nov. 
sc n 
the lower ovate or triangular, connate, I-2 mm. long; leaves 
5-8 cm. long; leaflets nine to eleven, oblong to oval, often retuse 
or emarginate, 5-12 mm. long, 2-4 mm. wide, glabrous above, 
I mm. long; corolla purplish; banner 8-9 mm. long, obovate; 
wings 7-8 mm. long, the blade obliquely oblanceolate, with a 
long basal auricle; keel-petals slightly shorter, with a rounded 
apex; pod black-hairy, sessile, 8 mm. long, 3.5 mm. wide. 
Type collected at Fort Selkirk, Yukon, July 20, 1899, 
Tarleton 128, a & b (herbarium of the New York Botanical 
Garden). The following specimens in flower may belong here:—
