LEGUMIXOSAE 



Yar. fimbriatum Jepson comb. n. Leaflets spinulose-margined, acute or acuminate, recurved 

 at tip (in extreme form), 1 to 1^ inches long; involucre divided into entire subulate divisions. — 

 Wet meadows and margins of streams, 4000 to 7500 feet: Sierra Nevada from Tulare Co. to Sis- 

 kiyou Co.: Bubbs Creek, Fresno Co., Jcpso7i 784; Honey Lake Valley, Davy 3347; Forestdale, 

 sw. Modoc Co., il. S. Bahcr ; Sisson, Siskiyou Co., Jepson 13,650. 



Var. kermedianum Jepson comb. n. Dune Clover. Plants 2 to 6 inches high, the stems 

 often erect; leaflets obcordate, 2 to 4 (or 9) lines long; involucres sometimes much reduced in 

 size and sometimes with simple teeth. — Sand dunes along the coast: Del Norte Co. to Monterey 

 Co. May-Aug. The involucres are not often reduced to the minute size of those in the type speci- 

 mens of this variety; or again, involucres nuich reduced may occur in plants having the habit 

 usual to the species rather than to the variety.
