370 COMPOSITE. 



cinereous-tomentulose oblanceolate leaves recurved at tip aud mucro- 

 nate: beads few aud elongated {^i ia. high), somewhat thyrsoidly or 

 even racemosely disposed; bracts of the involucre tomentulose, ending 

 in a long rigid recurved acumination: corollas merely ochroleucous. — 

 Valley of the Truckee River, and in Plumas Co., always east of the 

 Sierra Nevada. 



10. C. Bolanderi, Greene, 1. c; Gray, Proc. Am. Acad. vii. 354 (1868), 

 xinder Linosyris. Stout aud low, only a few inches high, the stem 

 woolly but leaves green, glabrate and viscid, oblanceolate, obscurely 

 3-nerved: heads few and large (% in. long); bracts of the involucre 

 rather few and thin, lanceolate, with a soft acuminate apex, some of the 

 outer and shorter herbaceous-tipped. — Subalpine or alpine in the higher 

 Sierra, about Mono Pass, etc. 



11. C. cerumiiiosns, Greene, 1. c. 94; Dur. & Hilg. Pac. R. Rep. v. 



9, t. 6 (1855), under Linosyris. Early glabrate (or perhaps never tomen- 

 tose) and balsamic viscid, 2 ft. high or more : leaves scattered on 

 the slender fastigiate branches, spreading or recurved, almost filiform: 

 heads cymose-fascicled, about 5 lines high; viscid involucral bracts, 

 narrowly lanceolate, abruptly ending in a spreading setiform tip: corolla 

 deeply cleft. — Apparently a very local species of the region of the Tejon 

 Pass; perhaps of the more typical group of the genus. 



-I— -1— Heads with some ligulate ray-corollas. 



12. C. Bloomer i, Greene, 1. c. 115; Gray, Proc. Am. Acad. vi. 541 

 (1865), under Aplopappus. Usually glabrous and resinous, sometimes 

 tomentulose, 1 — 2 ft. high, with erect rigid virgate branches abundantly 

 leafy: leaves spatulate-liuear to almost filiform, 1—2 in. long: heads 

 thyrsoidly or almost racemosely disposed, 9Ji iu- high; inner bracts of the 

 involucre oblong-lanceolate or linear, with thin-scarious erose-ciliate 

 margins, some of the outer with filiform herbaceous tips: rays 1 — 4: 

 achenes sparsely pubescent. — Eastern foothills of the Sierra Nevada, 

 from Kern Co. northward. 



14. CHRYSOMA, Nnttall. Evergreen shrubs of low stature, with 

 narrow entire mostly subterete punctate leaves, and terminal cymose or 

 corymbose chisters of small heads. Involucre turbinate; bracts mostly 

 lanceolate, very regularly imbricated, margins subscarious. Flowers 

 yellow, none turning red or brown. Disk-corollas slender-tubular with 

 subcampanulate throat and deeply cleft limb. Style-appendages fili- 

 form, acuminate, hirsutulous. Achenes more or less distinctly prismatic. 

 Pappus of scabrous slender bristles dull-white or yellowish, becoming 

 reddish.
