SMITH: STUDIES IN THE GENUS LupINUs—IX 383 
have much to do with the stature, size of leaflets, length and 
density of pubescence, and, perhaps, color of the seeds. Watson’s 
characterization of the variety is not much in itself, but I am 
satisfied that the plants assigned here include the form for 
which Watson borrowed Nuttall’s manuscript name. The 
original description is as follows: 
(L. microphyllus, Nutt. Hees: A lower and more hirsute form, with 
leaflets 3-6 lines long. San Dieg : 
L. rostratus Eastwood is, as g] see it, a teratological variation, 
in line with L. scaposus Rydb. (see Bull. Torrey Club 46: 397 
191Q). 
This is the dominant variety in Southern California, where 
it has long teen known as L. micranthus. From this region, 
where it is evidently very common, it extends locally northward 
as far as southern Oregon. I include here two of Greene’s 
manuscript species.
