INTRODUCTION 
The three groups treated in this paper have little in common 
except that they are annuals or biennials with non-verticillate 
flowers. Each group is monospecific, as I see it, but botanists 
have seen as many as six species in the variable L. concinnus and 
four species in the likewise variable L. subcarnosus. 
These groups may be contrasted as follows: 
Racemes shorter than their peduncles; keel petals densely ciliate near 
he claw, on both upper and lower edges. STIVERSIANI. 
Racemes longer than their peduncles; keel petals naked on both 
upper and lower edges. 
Leaflets 2-5 mm. wide; pods 10-15 mm. long; seeds 1.5—3 mm. 
long. CONCINNI. 
* Leaflets 6-12 mm. wide; pods 30-50 mm. long; seeds 4-6 mm.

Erect, the few to several branches ascending, 15-45 cm. tall,
