268 BOTANY. 



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

 Var. DIFFUSA by Dr. Gray, but as "too near small forms of the last." They 

 are apparently only an early undeveloped state of O.Jioccosa. (915.) 



GiLiA GuNNisoNi, T. & G. Grmj, I c, p. 273. Annual, a span high, 

 slender, more or less woolly-pubescent when young, at length almost glabrous, 

 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 

 longer than the oval or oblong lobes ; stamens shorter than the lobes, inserted 

 in or near the sinuses ; anthers ovate ; cells 2-3-ovuled. — Sandy banks of

GiLiA CONGESTA, Hook. Gray, I. c, p. 274. Perennial, more or less 

 woolly-pubescent, stems 3-12' high, erect or spreading from a tufted base, 

 bearing single terminal or few and corymbose close heads ; leaves alternate, 

 pinnately parted with 3-7 mucronate linear segments, or some of them entire; 

 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 equaling the anthers ; cells 2-4-ovuled. — From Colorado to Oregon 

 and the Sierras. From Roberts Station to Holmes Creek Valley, on the 

 foot-hills and mountains ; 6-10,000 feet altitude; July-September. (916.) 



Var. CEEBEIFOLIA, Gray. Depressed and csespitose-crowded; stems 

 many, 2-3' high, crowded with glabrous or slightly woolly subulate entire or 

 trifid leaves ; bracts subulate, short; flower-clusters solitary. — Southwestern 

 Wyoming, (NuttaU.) Foot-hills of Bear River Valley, Utah, near Evauston; 

 6,000 feet altitude ; July. (917.) 



GiLiA PUMILA, Nutt. Gray, I. c, p. 274. Annual; stems loosely 

 woolly, at least when young, leafy, 3-4' high ; leaves alternate, narrow-linear, 

 entire, or pinnately 2-5-parted with diverging linear mucronate lobes ; flowers 

 leafy-bracted, cymose-clustered or at length loose ; corolla white, salverform, 

 the tube 3-4" long, about thrice exceeding its lobes and twice longer than 

 the short-awned calyx-lobes; filaments slender, inserted at the sinuses, 

 shorter than the corolla-lobes ; cells about 6- (sometime 2-3-) ovuled. — From 

 Western Nebraska and Wyoming to Western Texas and New Mexico.
