or two small pointless ones. — Foothills of the Sierra in Merced and 

 Tuolumne counties. 



4. C. cilios.i. Simple, or toward the summit somewhat virgately 

 branching, 1 — 2 ft. high, strigose-pubescent and sparsely pilose: leaves 

 1 — 2 in. long, scabrous and scabrous-serrulate, the short fascicled and 

 floral ones tipped with a subsessile gland and densely hirsute-ciliate; 

 united bracts of the receptacle about 5, nearly truncate and mucronate, 

 woolly-ciliate within at apex: rays 3, their black achenes smooth and 

 glabrous; those of the disk hairy on the angles, their pappus of alter- 

 nately short and blunt and aristate-acuminate paleae. — Lake and Hum- 

 boldt counties, Priitgle, Chestnut cfc Drew. 



5. C. bicolor. Seldom more than a foot high, erect, simple, scabrel- 

 lous throughout: leaves very narrowly linear, 2 — 3 in. long, mostly with 

 a few scattered setiform hairs along the margin near the base; the fasci- 

 cled and floral short ones gland-tipped, and those next the involucre 

 with small glands up and down the back, the margins sparsely setose- 

 ciliate: cup of the receptacle as in the last, but less strongly woolly- 

 ciliate: rays 2 or 3, cream-color (drying yellow), red at base: ray- 

 achenes semiobovate, carinate-nerved on the back, more or less strigose- 

 pubescent, especially about the summit; disk-achenes also with flattened 

 ventral face, this pubescent, the back usually glabrous; pappus of about 

 10 unequal palese, 2 or 3 being short and acute, the others though un- 

 equal all much longer and aristate-acuminate. — Very common upon a 

 narrow belt of the Sierra foothills from Butte Co. to Calaveras. Herbage 

 with the offensive odor of Hemizonia luzulsefolia. 



6. C. liispula. Hemizonia hlspida, Greene, Bull. Torr. Club. ix. 63 

 (1882). Stout and rigid, l^^g — 3 ft. high, scabrous-pubescent and hispid, 

 virgately short-branched and floriferous almost from the base: leaves 

 narrowly linear, 7 — 3 in. long, hispid-ciliate toward the base, those of 

 the axillary fascicles shorter and with a tack-shaped gland at apex, the 

 floral bracts hirsute-ciliate throughout: cup of receptacle acutely about 

 10-toothed: rays 3—5, sulphur-yellow, large and showy; their achenes 

 with a more or less conspicuous appressed pubescence: disk-achenes 

 similarly pubescent throughout, and with a pappus of narrowly linear- 

 acuminate subequal paleae of twice their own length. — Sandy plains of 

 the middle and lower San Joaquin. A gigautesque and very distinct 

 species, apparently somewhat local. Heads mostly glomerate on short 

 branches. 



* * White-flowered species. 



7. C. campestris. Near C. hispida, but rather slender and not virgate,
