 so in No. 10) : heads small, 5-flowered.

1. B. Menziesii, Gray, 1. c. Shrubby at base, a foot or two high, nearly gla- 

 brous, often a little glutinous : leaves spatulate or lanceolate, rigid, spinulose-serrate 

 or pinnatifid-toothed : heads in small clusters terminating leafy branches, nearly 

 half an inch long, 12- 20-flowered : scales of the campanulate involucre numerous 

 and regularly imbricated, coriaceous, with obtuse or rounded abrupt green tips : 

 style-appendages short and broad : akenes short-linear, silky-hirsute : pappus rather 

 rigid, Pt/rrocoma Menziesii, Hook. & Arn. Aplopappus (Aplodiscus) Menziesii, 

 Torr. & Gray, FL ii. 242. 



Southern part of the State, extending into Arizona and Utah, and along the coast from San 

 Diego to Santa Barbara, and perhaps farther north. Variable in foliage, &c. To this may pos- 

 sibly belong Liiwuyris dentatiis, Kellogg, Proc. Calif. Acad. ii. 16, from Cerros Island, Lower 

 California. 



2. B. arborescens, Gray, 1. c. Shrubby, with numerous tufted erect branches 

 on a short tree-like stem, 3 to 9 feet high : leaves very numerous, 2 to 4 inches 

 long, very narrowly linear or soon by revolution of the margins becoming filiform, 

 resinous-punctate, glutinous : heads numerous in crowded corymbs terminating 

 paniculate branchlets, 20 - 25-flowered, barely 3 lines long : scales of the turbinate 

 involucre numerous and regularly imbricated, lanceolate, acute, destitute of green 

 tips : style-appendages lanceolate-subulate, little shorter than the stigma-bearing 

 portion : akenes turbinate, minutely silky-pubescent. Linosyris arborescens, Gray, 

 in Bot. Mex. Bound. 



Dry hills through the Coast Range, Santa Cruz to Tamalpais. Except in the woody trunk, 

 this resembles a Solidago of the Euthamia section ; and, indeed, a specimen collected by Prof. 

 Brewer shows a decided tendency to form rays ; so that it may have to be transferred to that 

 genus. But the shrubby character and the unequal bristles of the pappus are more congruous 

 with the present genus. 



3. B. Cooperi, Gray, 1. c. Shrubby, apparently low : leaves (only those of the 

 branches known) linear-filiform, thickish, obtuse, resinous-punctate, glutinous, about 

 a quarter of an inch long : heads few in the terminal clusters, 6 - 7-flowered, 3 lines 

 long : involucre narrow ; its scales rather few, regularly imbricated, oval or oblong, 

 chartaceous, destitute of green tips : style-appendages short, triangular-ovate : akenes 

 turbinate, silky-villous, 10-ribbed. 



Eastern slope of Providence Mountain, in the southeastern borders of the State, Dr. J. G. 

 Cooper. Resembles B. ericoides, which has the 4-ranked involucre and filiform style-appendages 

 of another section : also resembles B. diffiisa, Gray, of N. W. Mexico (mentioned in foot-note on 

 the preceding page), which has more slender leaves with acute and recurved tip, blunter and 

 greenish tips to the involucre, and deeply-cleft corolla. 



4. B. Bolanderi, Gray, 1. c. Shrubby, a foot or two high, slightly viscid-glandu- 

 lar, except the branches, which are coated with a close matted white wool : leaves 

 spatulate-linear or oblanceolate, about an inch long, not rigid, rather indistinctly 

 3-nerved : heads several in a corymb-like or somewhat racemose cluster, 711- 

 flowered, nearly three fourths of an inch long : involucre narrow ; its scales about
