nearly pflabrous : leaves linear to narrowly lanceolate, 1 — 2 in. long, 

 obscurely denticulate, the lower on long and slender petioles : petals 

 ligbt-purple, ^^ — '^4 in. long, cuneate-obovate, deeply 2-lobed : capsule

 short pedicel. ^From Nevada Co. to Tuolumne in the Sierra, at low 

 altitudes ; also plentiful in the Briones Hills of the Mt. Diablo Kange in
