throughout: stems numerous, decumbent, 2 feet high, rather 

 slender: leaves, even the lowest, palmately 5 — 7 -parted, the 

 •cuneate divisions 3 — 5-lobed or -toothed, or those of the 

 uppermost entire: raceme simple, loosely flowered: divisions 

 of calyx attenuate-acuminate : corolla deep purple, the lobes 

 obtuse, or at most only truncate : reticulations distinct and 

 elongated lengthwise of the carpels. 



Sierra Nevada, at about 6,000 feet altitude, and ranging 

 from Mt. Shasta to Kern County. Very common about 

 Summit station, in the neighborhood of Donner Lake, where 

 it was collected by Mrs. Curran and the writer, in August, 

 1883. One of the best species, readily known by its pale, 

 glaucous hue, and the peculiar, geranium-like foliage. To 

 the unassisted eye the plant looks perfectly smooth; but a 

 good lens reveals on all parts of the stem and foliage, the 

 pubescence above described. 



S. asprella. 



Deep green; roughish throughout with a short, stellate 

 pubescence : stems several, simple, decumbent, leafy up to 

 the slender raceme: leaves 2 — 3 inches wide, truncate at 

 base or with a broad sinus, lightly 5-lobed, the broad lobes 

 each with about 5 rounded teeth : divisions of calyx triangu- 

 lar-lanceolate, acute: corolla purple, an inch long, its lobes 

 truncate, erose: carpels large, transversely rugose, depressed. 



On bushy hillsides of the lower Sierras, just below the 

 habitat of Chamcebatia; apparently not collected before last 

 season; found by Mrs. Curran in El Dorado County, and by 

 the writer on Mr. John Eamm's ranch, near Camptonville, 

 in Yuba County. Peculiar, at least among the perennial 

 species, in having its leaves all of precisely the same shape, 

 the lowest and the uppermost differing only in point of size. 

 The rough pubescence is likewise very characteristic.
