80 BOTANY OP THE DEATH VALLEY EXPEDITION. 



Davenport Academy, vol. v, p. 172: " I am led to the conclusion that they properly 

 belong to one species, of which it would he possible to make many varieties." Speci- 

 mens were collected in the valley of the Kaweah River (No. 13S1). 



The varietal name originally published was evidently intended for parvifolius, and 

 was afterwards so written by its author in the Botany of California, vol. i, p. 102. 



Ceanothus pinetorum sp. nov. Plate VI. 



Plant of the sub-genus Cerastes, 0.6 to 1 meter high, densely branched; brandies 

 divaricate, dark brownish red when young; leaves opposite; stipules at maturity 

 nearly as thick as broad, ovate in outline, acute, divaricate, reflexed, from 2 or 3 to 

 5 nun. long, light brown, glabrous, spongy, and when old powdery within; petiolo 

 1 to 2 mm. long; blade broadly oblong, rounded at base and apex, 0.5 mm. thick, 

 commonly 12 to 16 mm. long, glabrous or with traces of early pubescence, spinulose- 

 dentate, with 4 to 6 teeth on each side, the under surface venose- reticulate, with 

 minute white areola*; flowers not collected; fruiting peduncle 0.5 to 1,5 cm. long, 

 about 2 mm. thick; fruiting pedicel of about the same length, somewhat slenderer; 

 fruit 7 to 9 nun. long in addition to the crests, these about 3 mm. long; seed oblong, 

 about 4 mm. in length, black and shining at maturity. 



Typo specimen in the United States National Herbarium, No. 1738, Death Valley 

 Expedition; collected August 30, 1891, near Lyon Meadow, Sierra Nevada, Tulare 

 County, California, by Frederick V. Coville. 



The species was seen only in the forests of Pinus jeffreyi,. on the headwaters of 

 Kern River, in the valley that lies between the two main crests of the Sierra Ne- 

 vada. The very large fruit, the form of the leaves, and the erect habit of the plant 

 distinguish it from all the species of the sub-genus. In our specimens the conspicu- 

 ous enlargement of the stipules is remarkable. 



Ceanothus vestitus Greene, Pittonin, ii. 101 (1890). Typo locality, "borders of 

 pine forests on the mountains near Tehachapi, Kern Co., Calif." 



Ourplant agrees well with Professor Greene's description, buttbeleaves are smaller 

 than in his type specimens. The species occurs at a higher altitude than C. cunealus, 

 growing, where we found it, on the tops of hills a short distance below the zone of 

 Pivutt Jeffrey! , a range according with thatgiven by Professor Greene. On thesummita 

 of some of the mountains south of Fort Tejon (No. 1194) this shrub, together with 

 Cercocarpus parvifoliua and Fremontodendron califonricum, forms a dense chaparral 

 a little below the limit of the black pine. It was seen only in this locality. The 

 identification of the specimens was authenticated by Professor Greene. 



AMPELIDACE.5J. 



Vitis californica Benth. Bot. Sulph. 10 (1844), under Vitex ; Bonth. PI. Ilartw. 

 302 (1848). Type locality, " Rio Sacramento." 



The wild grape was found at Ash Meadows; at a monad spring near Vegas 

 Ranch; in Surprise (No. 626), Willow Creek, and Mill Creek canons, Panamint 

 Mountains; in the Canada de las Uvas; at Tejon Ranch; and in the valley of the 

 Kaweah, between Three Rivers and Kano Flat. 



SAPINDACE^!. 



.ffisculus californica (Spach) Ann. Sci. Nat. ser. 2. ii. 62 (1834), under Calothyr- 

 ew; Nutt. in Torr. & Gr. PI. i. 251 (1838). Type locality, "in California." 



This tree, the buckeye, does not occur east of the Sierra Nevada. It was tirst seen 

 near Havilah, in Kern County (No. 1076). From that point south to Fort Tejon it waa 

 found abundantly, and again along the Kaweah River in the foothills of the Sierras. 

 All these localities are on the western slope of the Sierra Nevada below the belt of 

 chaparral.
