species. The little pubescence on the lower surface of the leaves 
and the calyx and pod is similar to that of H. curvicarpus but 
sparser. The pod, however, is more like that of H. Gibbsii. 
Besides the type the following specimens belong here: 
OREGON: locality doubtful, Lloyd, in 1898; Moro, N. Morri- 
son, in 1894; Eastern Oregon, Cusick 1878. 
55. Homalobus speirocarpus (A. Gray) Rydb. comb. nov. 
Astragalus speirocarpus A. Gray, Proc. Am. Acad. 6: 225. 1866. 
Gray formed a section from this and H. podocarpus on account 
of the thick sutures, which according to him separate from the 
valves of the pod, a character which is not manifest in the her- 
barium specimens seen. The flower of this as well as of H. podo- 
carpus is the same as that of H. collinus and H. Gibbsii, and the 
pod of H. spetrocarpus is practically the same as in the latter 
species except that it is longer, more reticulate and more curved 
often forming two almost complete circles.

in 1882; North Yakima, Griffiths & Cotton 45; Natchey Valley, 
Pipzr 2758; Wenash, Lyall; Yakima County, Henderson Bysi 
Brandegee 32, 728; Morgans Ferry, Suksdorf 277. 
56. Homalobus alvordiensis (M. E. Jones) Rydb. comb. nov. 
Astrazalus alvordiensis M. E. Jones, Contr. West. Bot. 10: 67. 
1902. 
Notwithstanding the fact that-the author placed this species 
in another part of the genus A stragalus*, the species is evidently 
closely related to the preceding, differing in the small flowers and 
fruit. The latter is similar, less spiral and more turgid. It is 
known only from the type locality. 
57- Homalobus podocarpus (Hook.) Rydb. comb. nov. 
Phaca podocarpa Hook. Fl. Bor. Am. 1:142. 1831. Not Asira- 
galus podocarpus Meyer, 1831. 
Astragalus sclerocarpus A. Gray, Proc, Am. Acad. 6: 225. 1866. 
Though the specific name podocarpus is not available in 
Astragalus, it is in Homalobus. The pod is quite different in 
* Jones has corrected this error in his recent ‘“Revisicn’’.
