TyPE collected east of Heffner, Oregon, W. E. Lawrence 744 
(herbarium of the New York Botanical Garden); also at the

50. Homalobus Gibbsii (Kellogg) Rydb. comb. nov. 
Astragalus Gibbsii Kellogg, Proc. Calif. Acad. 2: 161. 1862. 
Astragalus Gibbsii was described from the headwaters of the 
Carson River. Since Kellogg’s description is not complete and 
since his figure does not show any fruit it is a little doubtful if 
his plant was the same as the plant usually regarded as this 
species. This plant was collected by Anderson at Carson City 
and described by Gray* who included it under A. cyrtoides. 
It is, however, not the original A. cyrtoides A. Gray,f{ for this 
is described as having linear-oblong leaflets glabrous above, 
which fits only H. collinus and H. californicus among the species 
of thisgroup. As, however, the fruit of A. cyrtoides was unknown, 
the identification has remained doubtful; but the type resembles 
1. collinus so cree that I do not hesitate to refer it to that 
species.
