374 SmiItH: STUDIES IN THE GENUS Luprnus—IX 
straight, the slender acumen well defined, ciliate above between 
i and apex; pods 15-20 mm. long —5 mm. wide, ap- 
pressed-hairy, ovules five to eight; seeds rhombic or elliptic- 
oblong, 2-3 mm. long by about 1.5 mm. wide, pale flesh-color, 
pearly-white, or grayish, unmarked or dotted or mottled with 
gray or brown, with or without an oblique lateral line. 
feller’s recent review of this species (Muhlenbergia 7: 6. 
1911) permits me to omit here quotations from the original 
description and detailed references to the older literature.

I can easily accept his conception, as to the typical form of the 
species, but I cannot follow his idea as to its limitations. Since 
my former published reference to this species (Muhlenbergia 6: 
137. 1911), I have had much more experience with it both in 
the field and the herbarium, and now see it as another of those 
species which consist of a large number of mutating or inter- 
grading forms which almost defy classification. As in L. sparsi- 
florus, L. concinnus, and L. nanus, the wide variation in the shape 
of the leaflets in L. bicolor has much tempted me to recognize 
several varieties additional to those distinguished below; but 
here, especially, the inconstancies evident have led me to trim 
the list to just seven forms.
