SMITH: STUDIES IN THE GENUS LUPINUS 11 
The calyx is mostly 7-9 mm. long, the teeth of the lower lip 
are about 1.5 mm. long, commonly slender and curved-diverging, 
and the interstitial ‘‘cusp’’ is conspicuous. The flowers vary 
from dark red to merely pinkish. The seeds are yellowish gray 
to flesh-color, about 3.5 mm.x 3 mm., flattish, coarsely rugose, 
unmarked or nearly so. JL. brevicaulis, with which Heller com- 
pares the plant, is a member of the Pusillt.

[Fic. 5.] 
I quote from the original description, as follows: 
Branches several, all floriferous ... the lowest ones hor- 
izontal, the ones above them more ascending, the middle 
ones erect . .. lower lip of calyx green, pubescent with 
somewhat ae, hairs, ovate-lanceolate, 6 mm. long, over 3 
mm. wide at base, barely acutish, the apex minutely 2-tooth- 
, 
ed; upper os ovate, membranous, barely 2 mm. long, cleft 
nearly to the base, the lobes lanceolate with rather wide () Sie 
sinus. villous and ciliate: flowers pale violet-blue, whorled roe ne 
and crowded . erect, I cm, long, 7 mm. across; banner 
plane or only slightly turned back, with a prominent mid- 
vein; wings . 2 mm. wide keel not much curved, 
ciliate on the ‘ie third . . . seeds nearly 3 mm. across 
marked with small dark spots. 
I accept this as a well-marked species. It is oo. 
probably peculiar to the region of the type local- oxiontaris Heller- 
ity, though represented southeastward by adis- A. ‘ean 7725 (G).
