Actinella. COMPOSITE. 393 



Meadows and swamps near the sea, in Mendocino and Humboldt Counties, Botander. A most 

 striking large-flowered species. Kays an inch long when well developed. Disk at lirst depressed- 

 hemispherical, becoming globular in fruit : the summit of the peduncle thickened under it. 



* * Heads rather large, the globose disk half an inch or more wide, and the rays half 

 to three fourths of an inch long: root perennial : herbage glabrous or minutely 

 pubescent. 



3. H. autumn ale, Linn. Stem leafy to the corymbose summit, a foot to 3 or 

 4 feet high: leaves broadly lanceolate (2 to 4 mches long), often serrate : beads 

 mostly several on slender rather short peduncles : scales of the pappus ovate or 

 ovate-lanceolate and awn-pointed, from half to two thirds the length of the corolla. 



Probably along the northern borders of the State, being common in Oregon (the var. gra 

 florum, Torr. & Gray), also in Nevada ; thence to the Atlantic States. 



4. H. Bigelovii, I Way. Stem from one to three feet high, commonly simple : 

 leaves lanceolate or elongated-oblong varying to linear, entire (3 to 6 inches long, 3 

 to 6 lines or rarely over an inch wide) : head on a slender peduncle from 3 to 18 inches 

 long : rays numerous, half an inch or more in length : disk depressed-globose, from 

 half to two thirds of an inch in diameter : scales of the pappus ovate-lanceolate or 

 subulate, tapering into an awn considerably shorter than the corolla. — Pacif. U. 

 Rep. iv. 107. 



Wit ground, Sierra to Yosemite Valley, &c., and westward to Lake Co. A very branching 

 specimen, with much shorter rays, collected by Prof. Bracer, (near Monterey .'1 may lie an extreme 

 form of tliis rather than of the following species. 



* * * Heads middle-sized <>r small: the rays shorter than the globose disk, about a 

 quarter of an inch or less long : root annual or biennial: stems loosely branching. 



5. H. puberulum, DC. Two to four feet high, paniculately much branched, 

 minutely cinereous-puberulent: branches terminating in long slender peduncles: 

 leaves lanceolate and entire, or the lower oblong and rarely incisely toothed, nearly 

 all much ileeurrent : involucre mostly short and inconspicuous, as also the reflexed 

 rays : scales of the pappus ovate, with a short mueronate tip or awn, one third or 

 one fourth the length of the corolla. 



Common along water-courses and shores through the western portion of the State, from San 

 Francisco Ray southward. Uisk half an inch or less in diameter. Rays 2 or at most ti lines 

 long, usually few. //. Jfexiamum, so called, in the Botany of Whipple's Expedition, from 

 Bohnas Bay, appears to be a form of //. puberulum, to which may also belong Coulter's No. 

 357, although it has mora slender rays and blunt pappus-scales. The materials of both arc 

 insufficient. 



6. H. laciniatum, Gray. A span or two high, branched from the base, 

 cinereous-puberulent 1 leaves lanceolate or linear, mostly laciniate-pinnatifid, little 

 decurrent, one or two inches long: scales of the involucre mostly longer than the 

 im\ -. dies,- shorter than the disk : scales of the pappus ovate, abruptly tapering into 

 a conspicuous awn, a little shorter than the. broad corolla, about the length of the 

 akene. — Proc. Am. Acad. i.\. 203. 



"California," probably on tin- southeastern binders, Coulter (No. ".".>;. 358). Yaqui River, 

 Sonora, l>r. Palmer. Peduncles about :'. inches long. Head with yellow disk 4 to 1; lines in 

 diameter; the rays 2 or 3 lines long. Disk-corollas a line long, their proper tube extremely 

 short. 



80. ACTINELLA, Xutt. 

 Mead many-flowered, with 8 to \2 pistillate rays; all the llowers fertile. Invo- 

 lucre hemispherical ; its scales in 2 or 3 series, nearly equal, ovate or lanceolate, 

 rigid nr ci iriaeei his (in- the inner with margins membranaceous), appressed. I.'eeep 

 tacle conical or strongly convex, naked, sometimes villous. Kays conspicuous, 

 3-toothed nr 3-lohed at the truncate extremity; disk-corollas ■ d-cylindra
