160 ANNALS OF THE MISSOURI BOTANICAL GARDEN 
Minas de San Rafael, Nov., 1910, Purpus 4920 (U. S. Nat. 
Herb. and Mo. Bot. Gard. Herb.). 
The outstanding characteristics of this species are the coarse 
pubescence with the unbranched rays, the perennial habit, the 
numerous cauline leaves, the doubly curved pedicels, the gla- 
brous, sessile pods, and the numerous ovules. Among the an- 
nual species it is sometimes confused with L. gracilis or L. Gor- 
donii. From both of these the sessile pods serve to separate it. 
The absence of a gynophore also distinguishes it from L. Lind- 
heimeri of the biennial or perennial species.
