RHAMNE^. 83 



small, crested. — Fot)t-lnlls of the Sierra in Amador Co., back of loue. 

 Parry, Greene. It is iu the State Survey collection under No. 4558. A 

 fine species, in habit different from any of those Coast Eange shrubs 

 which resemble it in foliage, and with which it was long confounded, 



8. C. velntiiius, Dougl. in Hook. Fl. i. 125. t. 45 (1830). Stout, 

 diffusely branching, 2 - 4 ft. high : leaves subcoriaceous, broadly oval, 

 13^2^ 8 in. long, shining and thick-glutinous above, more or less velvety- 

 pubescent and strongly 8-ribbed beneath ; petioles stout, i^ in. long : 

 thyrse compound, loose and broad, rather short-peduncled : fl. white. — 

 Higher parts of the Coast Range from Mt. St. Helena northward, and in 

 the Sierra from near Donner Lake. June. 



9. C. thyrsilloriis, Esch. Mem. Acad. Petrop. x. 285 (1826) ; Lindl. 

 Bot. Reg. XXX. t. 38 ; Nutt. Sylv. ii. 44. t. 57. Arborescent, 6—15 ft. high, 

 glabrous or nearly so, branches angular, foliage firm-membranous, 

 bright and shining ; leaves 1 — 2 in. long, short-petioled, ovate-oblong, 

 strongly 3-ribbed : thyrse dense, sometimes broader than long, on short 

 leaf>' peduncles : fl. deep blue : fr. small, smooth.— From Monterey 

 northward, preferring northward slopes and cool ravines ; very showy, 

 and said to have been cultivated in early days, but now seldom seen 

 except in its native wilds, and these wilds are now almost obsolete in the 

 vicinity of San Francisco. There are fine specimes on Angel Island. 

 In the Berkeley hills it is associated with C. soredialus, with which it 

 also hybridizes so freely that the undiscerning may regard the two as 

 confluent ; but the last named is of the rigid and spinescent group. 



•M- -M- ++ Leaves pinnate-reined ; margins glandular-toothed, undulate or 

 revolate ; surface mostly papillose or rugose. 



10. C. Parryi, Trel. Proc. Calif. Acad. 2d ser. i. 109 (1888). Arbor- 

 escent, 6 — 10 ft. high ; branches sparingly villous or glabrate, angular, 

 more or less papillose ; leaves subcoriaceous, oblong, obtuse, % — \% in. 

 long, the pinnate veins supplemented by a pair of laterals which run 

 near the more or less strongly revolute margin ; surface of leaf glabrate, 

 lower face more or less tomentose-canescent : thyrse narrowly oblong, 

 umbels subsessile : fl. blue : fr. small, smooth.— In the hill-country 

 between Napa and Sonoma counties, Mr. Rivers, Lr. Parry, northward (o 

 the interior of Hiimboldt Co., Marshall ; very closely allied to the next, 

 but probably distinct. The geographical ranges of the two are entirely 

 different. May, June. 



11. €. papillosns, T. & G. Fl. i. 268 (1838) ; Hook. Ic. PI. t. 272, and 

 Bot. Mag. t. 4815. Stouter than the last, less arboreous, 4^6 ft. high : 

 branchlets and stalklets hirsute-pubescent : leaves narrowly oblong, 

 1 — 2 in. long, glandular-serrate, the siirface rugose and glandular-papil- 

 lose : fl. blue, in short, mostly simple and short-stalked racemes : fr. 

 small, smooth. —Hills along the seaboard, from Monterey to San Francisco.
