6d. Lupinus bicolor Pipersmithii (Heller) comb. nov. [Fic. 88.] 
Lupinus Pipersmithii Heller, Muhlenbergia 7: 93. f. 16-17. 
IQII. 
Differing from typical L. bicolor in reduction of size of flowers 
which are from 5-8 mm. long, and in the non-ciliate keel. ° The 
seeds are usually pale flesh-colored, more or less mottled with 
yellowish-brown. 
When I first found this interesting variation, I really con- 
sidered it to be a worthy species (Muhlenbergia 6: 139-141. 
1911), in comparison with its relatives then known to me; but 
now, after much more extensive experience with it and L. bicolor, 
I must classify it where my judgment says it belongs. Except 
for the lack of keel-ciliation, it can not be distinguished from 
var. tridentatus at Antioch, Betabel, and San Juan, nor from var. 
microphyllus at many points in the San Joaquin Valley. It 
is the dominant form of L. bicolor in the last locality and 
seems to be local and less common elsewhere. Since Heller’s 
' description is readily available it is not reproduced here.
