Studies in the genus Lupinus—XI. Some new names 
and combinations 
CHARLES PIPER SMITH 
The lupines of California, Oregon, and Washington have not 
as yet been treated, as a unit, by any one writer. Numerous 
botanists, holding widely differing taxonomic views, have con- 
tributed much to the literature of this genus in these three 
States, some one hundred ten species having been described 
from California alone, and about fifty others from Oregon and 
Washington. Recently I have attempted to coordinate all of 
these propositions, with the natural result that I find it necessary 
to present some new names and combinations. Accordingly I 
here offer some nomenclatural adjustments, in advance of a 
general treatment that will Hecessarily, eceNes of its bulk, 
appear elsewhere.

Lupinus fruticulosus Greene; Muhlenbergia 8:-117.-- 192. 
The stoutest form of the species, with leanings toward L. 
aridus: flowers large and banner broad.
