acute, short acuniiuate, or the lowermost rather blunt, 5 to 8cm. 

 long, the blade tapering into the long petiole which about equals 

 the blade: stem leaves reduced to linear bracts 3 or 4 cm. long, 

 2 mm. or less wide: inflorescence about 14 cm. long, rather 

 loosely flowered: flowers large, 15 mm. long, about 6 mm. in di- 

 ameter, subsessile: calyx pale violet, clothed with soft white 

 chaffy hairs, the lobes oblong, obtuse, 12 mm. long, 3mm. wide, 

 concave or low canoe-shaped, the concavity i mm. deep: petals 

 i6mm. long, 3mm. wide at the middle, a little narrower at both 

 base and apex, the part included in the calyx with a broad green 

 band up the middle marked with three veins, the margins hya- 

 line; the exserted portion 4mm. long, spreading, purple, hyaline 

 margined: filaments awl-.shaped, 6mm. long, imm. wide at base, 

 .5 mm. at apex; anthers oblong, slightly auriculate at base, the 

 auricles rounded, 5 mm. long, i mm. wide throughout, inserted 

 on the filament i mm above the base: style 5 mm. long, i mm. 

 in diameter; stigma lobes 2, about .5 mm. long, blunt: fruit not 

 seen. 



The type, in the herbarium of the Nevada Agricultural 

 Experiment Station, is Heller 10^06^ collected June 25, 191 2, 

 at an elevation of 7500 feet, on the lower slopes of the White 

 mountains, Mineral county, Nevada. A few plants only were 

 found on a dry, stony, northeasterly exposure under and near 

 scattered juniper and nut pine trees 



This species is a near relative of C. crassicaiilis^ the type of 

 the genus, and by some may not be considered distinct. It dif- 

 fers, however, if the description and illustration in Stansbury's 

 Report 383//. /. can be relied upon, in the sinuate-dentate in- 

 stead of lyrate leaves with much enlarged terminal segment; 

 calyx lobes of equal width throughout instead of tapering to the 

 apex; p)etals of a more uniform width and not notched at the 

 apex; anthers of uniform width instead of tapering, and less 

 strongly versatile. It seems to normally be a much smaller 

 plant. Geographically it should be distinct, since comparatively 

 few species from the eastern borders of the Great Basin are found 

 on its western rim.
