Ceanothus. RHAMNACE^. 4^3 



tical to ovate, rounded at base and sometimes slightly cuneate along the strong lateral 

 nerves, very obtuse, usually entire or nearly so, microscopically tomentulose to glabrescent 

 and dull above, minutely tomentulose-canescent beneath, 1 to occasionally 2^ inches lonij 

 their slender slightly villous petioles sometimes half inch long : inflorescence finely velvety, 

 the short dense axillary clusters scarcely peduncled and aggregated into a rather dense 

 thyrsus 2 to 3 inches long : flowers white : capsules 2^ lines in diameter, depressed, verru- 

 cosely roughened, shallowly lobed at top. — Fl. i. 265 ; Wats. 1. c. 336 ; Trelease 1. c. 110 • 

 Parry, 1. c. 168; K. Brandegee, 1. c. 187. — California, in the Middle Coast Kange region. 

 In foliage and inflorescence smaller specimens approach C. cordulatus, while larger ones 

 recall the thicker-leaved 0. velutinus. 



C. Fendleri, Gray. Low and dense often prostrate shrub, with greenish very canescent 

 sometimes glaucous slender twigs ; the spines slender and sharp : leaves elliptical, rounded 

 or subacute at both ends, finely denticulate-serrulate or nearly entire, thin, green and spar- 

 ingly appressed-silky upon the upper surface, densely but microscopically gray-tomentulose 

 beneath, half inch to occasionally an inch long, their slender petioles 2 or 3 lines long : inflo- 

 rescence very short, mostly few-flowered : flowers white : capsules 2 lines in diameter, 

 smooth, somewhat acutely keeled at first, scarcely lobed at top. — J'l. Fendl. 29; Wats. 

 1. c. 337; Trelease, 1. c. Ill ; Parry, 1. c. 168; K. Brandegee, 1. c. 189.— S. Dakota, Bull 

 Springs, Rijdberg, no. 590, to New Mexico and Arizona. (Northern Mex.) With nearly 

 glabrous green twigs, red spines, and small broad leaves, it is var. vfuiDis, Gray in Tre 

 lease, 1. c. Ill, of S. E. Arizona, Lemmon, Greene, Toumei/. With leaves thicker, broadly 

 elliptical, rounded at both ends, finely tomentose on both surfaces and with veins very 

 prominent beneath, it is var. venosl'S, Trelease, n. var., which closely resembles some small- 

 leaved Oregon specimens referred to C. cordulatus, and occurs in Texas, Limpia Mts. 

 liavard, and Arizona, Ft. Whipple, Coues & Palmer, Sta. Catalina Mts., Lemmon. (Northern 

 Mex.) Specimens somewhat resembling C. ovatus occur in Colorado, Parry, 1864, Coal 

 Creek, Brandegee, 1881. 



-f— 6. Leaves medium sized or small, firm but rather thin, nearly all 3-nerved ; the margin 

 conspicuously glanduliferous rather than toothed : inflorescence subsimple, oblong, mod- 

 erately large : twigs terete, usually intricately branched and occasionally rigid but scarcely 

 spinose or pruinose. 



C. tonaentosus, Parry. Medium-sized shrub, with slender gray or reddish at first tomen- 

 tose mostly densely verrucose twigs : leaves elliptical to usually round-ovate, commonly 

 rounded at base and apex, very conspicuously glanduliferous on the margin, dull microscopi- 

 cally velvety and drying dark on the upper surface, densely brown- or commonly white- 

 tomentose beneath, 4 to 10 lines long (on suckers, and usually in the San Bernardino form, 

 1 to 1^ inches long and nearly as wide, and very coarsely dentate), short- petioled : inflorescence 

 loosely tomentose, 1 or 2 inches long ; flowers deep blue or exceptionally white : capsules 2 

 lines in diameter, somewhat depressed, smooth, slightly crested, evidently lobed. — Parry, 

 1. c. 190. C. oliganthus, var. tomentosus, K. Brandegee, 1. c. 198. C. azareus, Kellogg, Proc. 

 Calif. Acad. Sci. i. 55. C. sored iatus, Trelease, 1. c. 1 1 1 , in part ; Parry, 1. c. 1 69. — California, 

 from the Sierras of Amador Co. to San Diego. (Lower Calif.) Apparently uncommon in 

 the middle region. 



C. SOrediatus, Hook. & Arn. Pather low densely branched shrub, with olive or at length 

 purplish minutely tomentose and somewhat villous sparingly and finely red-warty commonly 

 very rigid twigs : leaves narrowly ovate to elliptic-lanceolate, rounded at base, frequently 

 acute, 4 to 10 lines long ; the margin about as in the last ; the convex upper surface mostly 

 at finst with a few rather short hairs, soon glabrescent, dull but looking as if waxed ; lower 

 surface darker green or gray and minutely appressed-silky ; the short petioles (like the 

 ))rincipal veins beneath) appressed-hairy : inflorescence nearly as in the last or smaller, at 

 first loosely villous : flowers deep blue : capsules globose, 2 lines in diameter, smooth or 

 somewhat wrinkled, neither crested nor deeply lobed. — Bot. Beech. 328,; Torr. & Gray, Fl. 

 i. 686, in part ; Wats, 1. c. 336, in part ; Trelease, 1. c. Ill, in part ; Parry, 1. c. 189. C. in-
