20 SMITH: STUDIES IN THE GENUS LUPINUS 
(Monterey County) are 4x3 mm., heavily marbled with dark- 
brown, the hilum area unmarked and pale. The variety is evi- 
dently confined to the upper Salinas Valley. 
Albilanatus is Latin for ‘“‘white-woolly, 
of the general pubescence in this plant.

The specimen is labelled ‘“‘Z. microcarpus, var.,’’ but is so dif- 
ferent from all other Chilean material seen by me that I think it 
best to set it apart as a variety of L. subvexus. The flowers be- 
come suberect soon after anthesis and have several characters in 
common with var. phoeniceus, but this differs in the greater number 
of whorls, more crowded above, in the very slender pedicels, and 
in the curved keel.
