 base, densely appressed silky- villous : leaflets 7 to 9, narrowly oblanceolate, f to 1^ 

 inches long, acute, on elongated petioles : bracts not exceeding the calyx, deciduous : 

 flowers verticillate or scattered, on short pedicels, in an elongated long-peduncled 

 raceme : upper calyx-lip toothed or deeply cleft : petals violet, the standard naked 

 and keel ciliate : pod an inch long. — Lindl. Bot. Reg. t. 1149 ; Watson, 1. c. viii.

Indian Valley, Plumas Co. {Mrs. M. E. Puhifer Ames) ; Sierra Co., Lemmon. Somewhat 

 resembling L. parviflorus on a reduced scale, but the fruit very distinct.

In the Sierra Nevada, near Carson City {Anderson) ; the variety, a very doubtful form near 

 Clark's Ranch in Mariposa Co., A. Gray. Scanty specimens of another allied form, densely hairy- 

 tomentose, with narrowly oblanceolate leaflets, have been collected by Rothrock on the North 

 Fork of Kern River, at 8,500 feet altitude. 



19. L. parviflorus, Nutt. Stems mostly solitary, strict, erect, slender, 2 or
