414 KHAMNACE^. Ceanothus. 



C. hirsutus, Nutt. Tall shrub or small tree : twigs clive, gray, or somewhat reddish, 

 irregularly but deusely villous, more or less red-verrucose, rather flexible : leaves ovate to 

 broadly elliptical, rounded or the larger cordate at base, obtuse to typically acute, half inch 

 to 2 inches long, rather short-petioled, the upper surface drying darker, conspicuously beset 

 with scattered appressed rather long hairs, the green or occasionally glaucescent lower sur- 

 face loosely hirsute, especially along the veins : inflorescence loosely puberulent-villous, 1 or 

 2 inches long, rather loose, subsessile : flowers deep blue to purplish : capsules somewhat 

 depressed, 2| to 3 lines in diameter, generally smooth, strongly crested, not conspicuously 

 lobed. — Nutt. in Torr. & Gray, Fl. i. 266 ; Wats. 1. c. 336, in part ; Trelease, 1. c. 1 11 , in part ; 

 Parry, 1. c. 169. C. oliganthus, Nutt. 1. c. 266 ; K. Brandegee, 1. c. 196, in part. — Coast Range 

 of Central California. The narrower-leaved form, which often has a smaller inflorescence, 

 is C. oliganthus, Nutt., which can hardly be separated. The species appears to hybridize with 

 C. spinosiis and the preceding species. 



Var. Orcuttii, Trelease, n. comb. Flowers paler blue : fruit strongly rugose and 

 loosely villous : otherwise like the type. — C. Orcuttii, Parry, Proc. Davenp. Acad. v. 193. 

 C. oliganthus, K. Brandegee, 1. c. 196, in part. — San Diego Co, California, Orcutt, 



-I— 7. Leaves medium-sized or small, mostly thin, not 3- nerved or some of them with a 

 pair of strong sub-basal lateral veins ; the flat margin minutely glanduliferous : inflores- 

 cence as in the preceding group, but rather smaller, sometimes subglobose : flowers deep 

 blue : twigs terete, not spiny, pruinose in only one species. 



C. diversifolius, Kellogg. Low and trailing, with green to reddish flexible irregularly 

 very villous sparingly verrucose twigs : leaves thin and flexible, broadly elliptical, rounded 

 or mostly acute at base, obtuse or suliacute, with the pubescence of the last on the upper 

 surface, but pale, often whitened and more or less loosely tomentose-villous beneath, short- 

 petioled, ^ to 1^ inches long, commonly (as in others of this section) with axillary fascicles of 

 smaller size : inflorescence about half inch long, elongating in fruit, with a peduncle of thrice 

 its length : capsules slightly pyriform, 2 lines in diameter, very smooth, somewhat evanes- 

 cently crested, slightly lobed. — Proc. Calif. Acad. Sci. i. 58 ; K. Brandegee, 1. c. 200. C. hir- 

 sutus, Trelease, 1. c. Ill, in part. C. decumbens, Wats. Proc. Am. Acad. x. 335 ; Trelease, 

 1. c. 112; Parry, 1. c. 168. — California, Sierras of the Yosemite region. 



C. Lemmoni, Parry. Low, spreading, but not decumbent, with gray or buff pruinose at 

 first tomentose slightly verrucose rigid twigs : leaves thicker, firm, elliptical, rounded or sub- 

 acute at both ends, 3 to 10 lines long, very short-petioled, finely appressed-pubescent to nearly 

 glabrous and dull waxen above, the lighter green to glaucous loosely villous lower surface 

 at length prominently reticulated : inflorescence about as in the last, but often shorter- 

 peduncled, exceptionally 3 inches long and somewhat thyrsoid : capsules as in the last, but 

 more strongly crested. — Proc. Davenp. Acad. v. 192. C. diversifolius, y&r. foliosus, K. 

 Brandegee, 1. c. 201, in part. C. decumbens, of other writers, in part. — N. Central Cali- 

 fornia, Lake and Butte Counties, &c. 



C. f oliosus, Parry. Rather low densely branched shrub : twigs greenish, gray, or red- 

 dish, slender but rather rigid, at first velvety or villous and mostly little verrucose : leaves 

 thin but ratlier firm, broadly elliptical, 2 to 6 (or the primary 10) lines long, mostly acute at 

 base, with obtuse or occasionally acute apex, on the darker upper surface with finer appressed 

 pubescence than in the last or glabrescent, appearing as if waxed, paler and often glaucous 

 beneath, with a few appressed coarse hairs along the veins : inflorescence scarcely half inch 

 long, becoming twice that length, little surpassed by the loosely villous peduncles : capsules 

 depressed, scarcely 2 lines in diameter, smooth, rather strongly crested, conspicuously lobed. 

 — Proc. Davenp. Acad. v. 172; Davy, Gard. Chron. ser. 3, xx. 363. C diversifolius, var. 

 foliosus, K. Brandegee, 1. c. 201, excl. syn. C. dentatus, Trelease,!. c. 112, in part. — Cali- 

 fornia, from the vicinity of San Francisco to Mendocino Co. What seems to be this species 

 also from Cuiamaca, Parish, no. 423. 



-1— 8. Leaves medium-sized or small, firm, usually not 3-nerved ; the upper surface strongly 

 glandular-papillate throughout or near the revolute glanduliferous margin : inflorescence 

 and twigs about as in the preceding group : flowers deep blue or exceptionally varying to 

 white.
