edly sometimes continued to the base, thus producing 2 distinct 

 paleae from one. But the paleae are always much narrower and 

 less obtuse than in C. suffrutescens. C. suffrutescens has been 

 re-collected (JuL, 1887, Brandegee, also Hall & Babcock, no. 

 4081) at what Mr. Lemmon, the discoverer of the species, informs 

 me is probably the type locality, namely, upper Shasta Valley at 

 about 1200 m. alt., and Mr. Lemmon has permitted me to ex- 

 amine the original specimens also. Although the pappus char- 

 acters are unsatisfactory, there are others which clearly mark 

 C. Parishii as a distinct species, particularly the smaller leaves 

 and their shorter divisions and the lack of all glandular pubes- 

 cence ; the peduncles and involucres of C. suffrutescens being 

 minutely but densely glandular after the fall of the tomentum. 

 In the latter species the involucral bracts are inclined to end in 

 foliaceous tips sometimes exceeding the disk, after the manner of 

 C. Xantiana, a tendency not yet observed in C. Parishii.

Erect from a perpendicular annual taproot, 3 to 15 dm. high, 

 simple below, branching above into a rather open leafless often 

 paniculate cyme: herbage furfuraceous-pubescent below, viscid 

 and glandular-hirsute above: leaves sometimes 2 dm. long and 

 two-thirds as wide but usually only half this size, 2 to 3-pin- 

 nately divided and parted, the ultimate divisions numerous and 

 irregularly oblong or linear: involucre about 1 cm. high; its 

 bracts linear-lanceolate, acute: flowers white: achenes attenuate 

 at base, flat, glabrous or nearly so : pappus of deciduous fimbri- 

 ate paleae or usually none. 



Bather common in the Upper Sonoran Zone away from the 

 sea ; from the Sierra Santa Monica to San Jacinto and south into 

 Lower California. Apr.-Jul. An exceedingly robust form has 

 been collected by Mr. Ernest Braunton in the Cahuenga Hills, 

 near Los Angeles (no. 273). One plant measures 16 dm. in 

 height, some of the leaves are over 2 dm. long, and the involucral 

 bracts are strongly reddish-tinged.
