close to it, and have been, and probably still will be, confused 
with same. Those, however, have the keel ciliate, and the pods 
and seeds as in typical L. bicolor. The species is evidently very 
local in the southern part of its range, as I have made three trips 
into the type region without finding a trace of it, and I also 
failed to find it where found by Bradshaw. It is scarce and 
very restricted at its Los Gatos station.
