Sericocarpus. COMPOSITE. 319 



* * Heads smaller and numerous, crowded in a pyramidal or elongated panicle. 



4. S. Californica, Xutt. Hoary or grayish with a fine and close pubescence : 

 JA^ stem strict, 1 to 3 feet high : leaves oblong, lanceolate-oblong and entire, or the 



lower spatulate or obovate and with a few scattered sharp teeth : heads in short 

 erect or barely spreading racemes, wliich are collected in a narrow close virgate or 

 pyramidal panicle: scales of the involucre lanceolate-oblong, acutish or obtuse, at 

 least the outer ones puberulent : rays 7 to 12 and about as many as the disk-flowers, 

 small : akenes minutely pubescent. — Varies with longer, more spreading, and then 

 commonly one-sided racemes. — S. petiolaris, Hook. & Am. in part. S. puberula, 

 Cham. & Schlecht. 



Var. Nevadensis. Hoary with minuter pubescence, smaller, with looser and 

 fewer decidedly one-sided racemes, the involucre mostly glabrous : approaching 

 S. nemoralis, but wants the canescent-silky akenes, &c. 



Dry ground, Santa Barbara to Sonoma Co. A California!) representative of S. nemoralis ; but 

 mostly more tall and strict. Like that, it has its greener and rougher [S. radula) state. The 

 heads of the latter sunn-times 4 lines long and full; ordinarily 3 lines long. Rays occasionally 

 abortive. Ileeeptaelc sometimes with alveoli extended into one or two awn-shape 1 seales, or else 

 bearing chaff resembling the inner seales of the involucre. Leaves one, two, or the lowest three 

 inches long. — The amliiguous var. Nevadensis, collected by Anderson near Carson City, and by 

 Dr. Horn in Owens Valley, &c. 



5. S. elongata, Xutt. Slightly and minutely pubescent, or nearly glabrous : 

 ty^ stem strict, very leafy to the top, 2 to 4 feet high : leaves green, rather thin, lanceo- 

 late or sometimes oblong, acute or acuminate, mostly serrate with some narrow and 

 sharp teeth (occasionally all the upper ones entire), triple-ribbed from below the 

 middle, veiny : heads very many, in compact erect or at length recurving racemes, 

 which are crowded in a narrow or pyramidal panicle : scales of the involucre linear, 

 small : rays 12 to 20, slender, usually more numerous than the disk- flowers : akenes 

 slightly pubescent. — S. stricta, Less. (?) 



Moist or shady ground, from above Monterey, and along the Sierra Nevada, to Oregon and 

 British Columbia. Heads 2 to 3 lines long. Var. mieruri-jihulii, Kellogg; a form with depau- 

 perate inlloreseence. 



6. S. Guiradonis, (hay. Completely glabrous : stem strict, slender, 2 or 3 feet 

 high : leaves bright green, thickish, entire; the upper linear and one-ribbed ; the 

 lower lanceolate or oblanceolate and tapering gradually into the long narrow base or 

 margined petiole, somewhat triple-ribbed : heads in a virgate panicle: seales of the 

 involucre lanceolate subulate : rays S or it, small: disk-llowers 10 or 12: akenes 

 almost glabrous. — Proc. Am. Acad. vi. 543. 



Base of San Carlos, Fresno Co. {fhiirado) \ Tejon, ,<cc., Bothrock. The var. sp . Eaton, 



in Bot. King., if of this species, as is likely, has broader and obtuser scales to the involucre, 

 broader lower leaves, &c, and answers to narrow-leaved forms of S. speciosa. It inhabits 

 Nevada, and probably occurs within the limits of California, 



7. S. sempervirens, Linn. Completely glabrous ; stem strict, and 2 or 3 feel 



high: leaves rather llcshy, lanceolate, entire, the lower tapering into long narrow 



ba e, the' uppermost reduced to subulate bracts of the virgate and rather dense 

 panicle: scales of the involucre lanceolate, obtuse: rays 8 to 10: akenes minutely 

 pubescent. 



Salt marshes mar San Francisco, Bolander. Near the southern boundary, 60 miles east of 

 San Diego, Palmer. Appears to be the same as the Salt-Marsh Goldcnrod of the whole Atlantic 

 shore down l" Mexico. It is a form with small heads (8 lines long), approaching S, angusltfolia 

 of Elliott 



19. SERICOCARPUS, Xees. 



Head 12-l. r >-flowcrcd, hcterogamous ; the rays about .">, distant, fertile, white, 



sometimes inconspicuous. Involucre oblong or narrowly campanulato ; its scales 



appressed, linear-oblong, arm-coriaceous or cartilaginous and white, with abrupt
