structure from all the preceding species of this group. Ita 
proaches that of H. Plummerae but is distinguished by the thicle 
sutures. The habit of the plant is more like that of H. collinus.

58. Homalobus bicristatus (A. Gray) Rydb. comb. nov. 
Astragalus bicristatus A. Gray, Proc. Am. Acad. 19:75. 1883. 
This species is evidently related to the preceding, the flowers 
being practically those of this group of Homalobus, but on account 
of its more turgid, leathery fruit it is somewhat anomalous in 
the genus.

59. Homalobus porrectus (S. Wats.) Rydb. comb. nov. 
Astragalus porrectus S. Wats. Bot. Kings Rep. 75. 1871. 
Tragacantha porrecta Kuntze, Rev. Gen. Pl. 947. 1891. 
This species is rather unique in the genus Homalobus. It 
the pod is taken into consideration, it might have been placed 
among the Collini as it is somewhat similar to that of H. Tweedy1, 
the stipe being ascending and the body erect; but the flower is 
not that of this group, for the calyx-tube is short-campanulate 
and the calyx-lobes elongate and of the same length, while the 
banner is narrow, retuse at the apex, and much longer than the 
other petals. It is therefore best to regard this species as con- 
stituting a section by itself. 
NEvapa: Trinity Mountains, S. Watson 284; Reno, Stokes, 
in 1900. 
The rest of the groups included by me in Homalobus, I rather 
think, should be removed from the genus. Astragalus loncho-
