SMITH: STUDIES IN THE GENUS LuprInus—IX 375 
I have much desired to allow L. sabulosus varietal rank, but 
the differentiating characters well shown by Heller’s drawings 
do not check up geographically. According to his drawings, 
his 10244, from San Francisco, distributed as L. sabulosus, must 
be called L. bicolor, while several specimens from northern 
California and Vancouver Island should be referred to L. sabulo- 
sus. In truth, variation in the shape of the banner and in the 
size and color of the seeds, as well as in the size and shape of the 
_leaflets, is rife in this species. Also the blue pigment is often 
missing from the petals, giving pink or white flowers. : 
L. strigulosus Gandoger is another extreme that, in itself, is 
perhaps possible of differentiation; but intermediates are numer- 
ous and make their classification a hair-splitting process. 
Specimens assigned to the species, sensu stricto, are:—
