SMITH: STUDIES IN THE GENUS LUPINUS 183 
Kellogg’s Napa specimen in the Gray Herbarium (Napa, dry 
barren hillsides, 1 Apr., 1870), though distributed by Kellogg as 
L. lacteus, cannot be referred here. It is possibly a diminutive 
specimen of var. perfistulosus of this paper.

Probably most closely related to var. lacteus, from which it 
would seem to be easily distinguished by the caulescent habit and 
the numerous racemes. It is noteworthy, however, that most of 
the specimens cited above were collected in June, while the types 
of both L. lacteus and L. arenicola were taken in April. It would 
therefore be an interesting study for some student to locate, if 
possible, the type station of Heller’s L. arenicola and Mrs. Brande-
