 ish with purple border, narrowly lanceolate-attenuate. Styles 2. Ovary wholly 

 free from the calyx, its 2 carpels lightly joined. — Species 2, California, Oregon and 

 Washington. (Dr. H. N. Bolander, botanist of the California Geological Survey 

 from 1865 to 1870.)

 leaves glabrous; leaf -blades round-cordate, ^/^ to 1% inches broad, 5-cleft, the seg- 

 ments rounded and shallowly lobed or toothed; petioles 2 to 4 inches long; upper 

 cauline leaves reduced, ovate, toothed, sessile; flowers 3 lines long; calyx-lobes and

Montane, wet rocks, 5000 to 8400 feet : central Sierra Nevada from Mariposa 

 Co. to Eldorado Co. May-July. 



Habitat note. — In our experience this interesting saxifrage is somewhat rare in individuals. 

 Always found in granite country, it grows like a fern under the edge of boulders, or on dripping 

 moss-covered rocks, or in rock crevices in moist situations, and may well be a glacial relic.
