Nevada ; June, July ; 5-6,000 feet altitude. The specimens are referred to

loosely paniculate-branched ; leaves scattered, entire, linear-filiform ; flowers 
in smaller heads, terminating slender peduncle-like branches ; bracts short, 
lanceolate, entire, short-cuspidate like the triangular calyx-lobes ; corolla 
white or nearly so, salverform, the tube slightly exceeding the calyx and 
lojiger than the oval or oblong lobes ; stamens shorter than the lobes, inserted

corolla white, salverform, the tube 2" long, about equaling the oval lobes, not 
exceeding the usually awned calyx segments ; filaments inserted in the sinuses, 
at length ecpialing the anthers ; cells 2-4-ovuled. — From Colorado to Oregon 
and the Sierras. From Roberts Station to Holmes Creek Valley, on the

Icafy-bractcd, cymose-clustercd or at length loose ; corolla white, salverform,
