specimens assembled on the sheet. The boundary line sep- 
arating Riverside and San Bernardino Counties passes through 
the Morongo country and it seems to be impossible to determine 
on which side of the line were taken the Morongo specimens here 
referred to San Bernardino County. 
Palmer’s specimen from Le Roy’s herbarium is a striking vari- 
ation towards L. odoratus and probably should have been given 
more serious attention here. 
Ioa. Lupinus oporATus Heller, Muhlenbergia 2: 71. 1905. 
[FIG. 48.] 
Nearly or quite acaulescent, glabrous or sparsely villous, 
1-2 dm. tall; peduncles commonly erect, equalling or exceeding 
the leaves, racemes 5-8 cm. lofig; flowers 10 mm. long, well-scat- 
tered; pedicels 4-6 mm. long, glabrous; calyx glabrous, upper 
lip about as broad as long, 2 mm. long, entire or notched, lower 
lip about 5 mm. long, entire or obscurely three-toothed; petals 
blue or purple, the banner with a yellow center, Io mm. long and 
10 mm. wide, wings 8 mm. long, 5-6 mm. wide, keel 7-8 mm. 
long, the point decidedly sees pods oblong, 17-20 mm. long, 
smooth or scaly on the sides, villous on the margins, ovules two to

This excellent species is of special interest both because of 
its number of ovules and its limited supply of hair-covering. 
The former character suggests relationship to certain species of 
the annuals of the subgenus Lupinus; but its cotyledons are 
sessile and its relationship is evidently closer to L. pusillus. There 
should be no further excuse for confusing it with L. brevicaulis.
