In the San Gabriel, San Bernardino and San 

 Jacinto mountains the leaves are sometimes puberu- 

 lent in varjing degree (var. puberulus Abrams). This 

 slightly pubescent state also occurs at various sta- 

 tions in the Sierra Nevada. A form with long and 

 narrow panicles on long (3 to 4 inches) peduncles 

 occurs in Shasta and Trinity Cos. (var. peduncularis 

 Jepson).

14. C. palmeri Trel. Cuyamaca Bush. (Fig. 232.) Shrub 4 to 7 (or 15) 

 feet high; bark grayish-green; leaf -blades oblong, obtuse at apex, light green above, 

 pale beneath, delicately but distinctly pinnate-veined, 2 to 12 (or 16) lines long; 

 panicles dense, 2 to 4^^ inches long, on short (I/2 to ll^ inches) leafy peduncles; 

 flowers white; capsules globose, 3-lobed, 2^/^ to 4 lines wide, the glandular crests 

 large. 



Montane ridges and slopes, 1400 to 6000 feet: Eldorado Co. foothills; San Ja- 

 cinto Mts. to the Cuyamaca Mts. South into Lower California. May-June. 



Geog. note. — In 1907, K. Brandegee collected on Sweetwater Creek in Eldorado County a 

 shrub with oblong leaves, which are obtuse at base and apex and pinnately veined. A. E. Wies- 

 lander found the same thing in 1927 on Flagstaff Hill between the North and South Forks of 

 the American River. These shrubs of Eldorado County are quite like the San Diego County 

 shrubs, whence came the original Ceanothus palmeri. It is not, however, unusual for a species 

 of San Diego County to reappear in the central Sierra Nevada foothills. For example, Ceanothus 

 tomentosus in somewhat altered form occurs in both coastal Southern California and in the 

 central Sierra Nevada foothills ; so do Jepsonia parryi and other herbs. It is worth noting that
