302 BOTANY. 



involucres sessile, 6-9, turbinate-campanulate, rather deeply 6-7-toothed, 

 thinly membranous ; bractlets shghtly bearded ; flowers with a broad or 

 rather shortly narrowed base, not produced ; calyx li" long, glabrous, dull- 

 yellow or rose-purple, the nearly equal segments obovate-subcuneate, emar- 

 ginate ; filaments nearly glabrous ; embryo as in the last. — Peaks and high 

 divides of 'the East and "West Humboldt and Clover Mountains, Nevada ; 

 8-11,000 feet altitude; July-September. (1,020.) 



Var. LAxiFOLiDM, T. & Gr. Taller, scape 4' high, branches of the caudex 

 more slender; leaves fewer, sublanceolate, acute, sometimes 1' long, on 

 slender petioles ; flowers golden-yellow. — A strongly marked form, found on 

 a rocky ridge of Stansbury Island, and in the Wahsatch, above Parley's Park;

Eeiogonum (Capitellata) elatum, Dougl. T. Sf G., I. c, p. 168. 

 Perennial ; leaves all radical, very softly villous-pubescent or almost velvety 

 beneath, ovate-oblong or sublanceolate, narrowed into a petiole, rarely sub- 

 cordate or subhastate at base, margins usually undulate ; scapes 1-3° high, 

 naked, rigid, rush-like, sometimes inflated ; involucres glabrate or glabrous, 

 few, cylindric or turbinate-campanulate, repandly 5-toothed, many-flowered, 

 gathered in heads or clusters upon a rigid panicle, sometimes only in pairs or 

 solitary in the forks and on rather longer pedicels ; bractlets plumose ; base 

 of the flower not produced ; calyx white or rose-colored, 6-parted, a little 

 hairy at base, the segments ovate-oblong, nearly equal ; ovary glabrous ; 

 embryo incurved ; cotyledons broad and short. — From Washington Territory 

 to California and Nevada. On the Virginia and "West Humboldt Mountains, 

 Nevada ; 7,000 feet altitude ; August, September. (1,022.) 



Eeiogonum (Fasciculata) fasciculatum, Benth. T. S^ G., I c, p. 169. 

 Shrubby, glabrous or subtomentose, the branches with numerous fascicled 

 leaves ; leaves small, oblong-linear or linear-spatulate, margins very revolute, 

 the larger ones attenuate to a short petiole; involucres many-flowered, 

 crowded in capitate usually 3-6-rayed cymes terminating the naked slender 

 peduncles, truncate, subdentate, the teeth at first membranously united; 

 calyx not produced at base, white or pinkish, the obovate-oblong segments 

 nearly equal; bractlets plumose; ovary glabrous; radicle accumbent-incurved 

 upon the rounded half-shorter cotyledons.— Southern California. Var. poli- 

 FOLiuM, Gray. Hoary throughout with a fine pubescence, the leaves some- 

 times glabrate above ; peduncles usually longer, 3-5' ; involucre-teeth not
