SMITH: STUDIES IN THE GENUS LUPINUS—VII 201 
follow Watson (Proc. Am. Acad. 8:538. 1873; and Bib. Index 
236. 1878) in assuming that this “is probably but a garden 
form”’ of L. densiflorus, nor accept his application of Agardh’s 
name to this species. Koch might have said more about the 
pods and seeds, but his “legumen . . . inter semina 
constrictum” and his comparison of the species with L. arvensis. 
L. ramosissimus, and L. Ehrenbergit do not point to a confusion 
with L. denszflorus. 
The species is so common in the San Francisco Bay region 
that I will omit citation of many specimens examined. An albino 
form (petals pale bluish white) was common in 1921, in and near 
the mouth of Alum Rock Canyon, Santa Clara County. This 
was mostly in pure patches, but sometimes associated with 
pale blue, or the normal, dark blue, form. Seeds were secured 
from marked colonies, but those from the palest-flowered plants 
were heavily pigmented, perhaps averaging even darker, rather 
than paler, than is normal for the species.
