COMPOSITE. 449 



down to the somewhat uuguiculate base. — Kern Co., at higher than 

 middle elevations of the Sierra, in pine woods or openings. 



82. HULSE4, Torrey A Oray. Herbs leafy, viscid and somewhat 

 balsamic-scented, or tloccose-woolly. Leaves alternate, sessile or nearly 

 so, entire, toothed or pinnatifid. Heads large, solitary or scattered. 

 Rays yellow or purplish. Bracts of the involucre thin-herbaceous, 

 linear to oblong, plane, in 2 or three series. Receptacle flat. Disk- 

 corollas with long narrow throat and 5 short lobes. Achenes linear- 

 clavate, or cuneate-oblong, villous. Pappus of 4 or 5 hyaline palefe 

 either erose or lacerate at summit, or dissected into capillary bristles. 



* Steins low, leafy at base, the merely bracted peduncles scape-like. 



1. H, vestita, Gray, Proc. Am. Acad. vi. .547 (1865). Rosette of 

 spatulate entire or dentate radical leaves pannosely white-tomentose: 

 flowering stem 1 ft. high, sparsely leafy below the middle, above scapi- 

 form and monocephalous, or bearing 2 or 3 long-peduncled heads: invo- 

 lucre }4 io. high, of broadly lanceolate viscid-pubescent bracts: rays 

 little surpassing the disk-flowers, or shorter, or even wanting, yellow 

 changing to reddish: pappus of quadrate erose palese, either nearly 

 equal, or 2 longer than the others. — Volcanic hills of Mono Co., and 

 southward. 



2. H. alg'ida, Gray, 1. c. Smaller, and from a deep perennial root- 

 stock; clothed with a villous or cottony wool which is caducous, and a 

 permanent viscid pubescence: leaves linear-ligulate, irregularly toothed, 

 the teeth sometimes large, the crowded lower ones 2 — 5 in. long: broad 

 involucre 1 in. high; its bracts linear, attenuate-acxite, loose, villous- 

 lanate and viscid: rays very many, narrow, }{ in. long, yellow: pappiis 

 short, not longer than the hairs of the achene, the palese deeply fimbriate- 

 lacerate. — Alpine summits of the Sierra, from Mt. Dana southward. 



3. H. nana, Gray, Pac. R. Rep. vi. 76, t. 13 (1857). Only a few inches 

 high, from long branching rootstocks, rising through volcanic ashes, 

 viscid-pubescent and villous-lauate: crowded leaves oblong-spatulate, 

 incised or pinnatifid, tapering to a marginal petiole: involucre % in. 

 high, of lanceolate bracts: rays 30, yellow: palese of the pappus usually 

 longer than the breadth of the achene, broad, or splitting into narrow 

 ones, incisely or fimbriately lacerate.— Summits of Lassen and Shasta 

 Peaks; in a form more woolly than the typical plant of the Cascades in 

 Oregon.
