young, becoming glabrous and glossy when old; petioles stout, 2 mm. long, 

 pubescent, with minute blackish glands intermingled; panicles short, on 

 rather stout peduncles; pedicels white, slender, glabrous, 5 mm. long; bracts 

 short, 2-3 mm. long, canescent at base and minutely glandular, the apex 

 brown, triangular-acuminate, deciduous; sepals green at base, thin and white 

 above, involute, surrounding the ovary after anthesis; corolla small, 5 mm. 

 long, with roundish, reflexed, ciliate lobes, externally glabrous, hairy within; 

 filaments dilated at base, glabrous; ovary glabrous or slightly pubescent, 

 conical; ripe berries glossy, reddish brown, variable in size and shape, 5-10 

 mm. in diameter, spherical or flattened either longitudinally or transversely, 

 the pyreniE either separable or coalescent into one, and extremely variable in 

 shape; pulp thin. 



This appears to be nearest to A. Hookeri, from which it 

 is chiefly distinguished by thicker, less veiny leaves, shorter 

 and stouter petioles, shorter bracts and longer pedicels, and 

 much thinner pulp. This manzanita loves the exposed 

 ridges, where the bluish gray volcanic rock crops out, and 

 is usually found associated with J^tiercus dumosa var. hul- 

 lata. The description was drawn from specimens collected 

 near the cypress trees on the trail between the Eldridge 

 Grade and Larsen's. It is abundant there, forming low, 

 spreading bushes not more than three feet in height. It is 

 also found around the reservoirs of the San Rafael Water 

 Company and along the road from Fairfax to Larsen's. It 

 is the last species in bloom, not coming into flower before 

 April. The fruit is ripe in September or October and per- 

 sistent for some time after ripening. The new growth is 

 made after the flowering period, the canescent leaves and 

 stems being very conspicuous contrasted with the dark 

 green, glossy, older foliage. 



Arctostaphylos canescens, sp. nov. 



Shrubby, forming erect or low, spreading bushes, densely clothed through- 

 out with short white curly hairs, with minute blackish glands intermingled 

 on the stem, petioles, pedicels, bracts, and lower surfaces of the leaves; 

 leaves oval, ovate, or obovate, shortly acuminate, mucronate, about 3 cm. 

 long, i^cm. wide, on stout petioles 5 mm. long; racemes few or solitary, 

 almost condensed into corymbs, with persistent foliaceous bracts 5-12 mm. 

 long, surpassing the stout pedicels, red-nerved and margined or rosy througli- 

 out; sepals oval, white or rose-color, ciliate, densely hairy within, usually 

 sparsely hairy externally, revolute, spreading after anthesis; corolla 7 mm.
