-Rhamnus pilosa (Trelease) Abrams, comb, nov. 
Rhamnus crocea, var. pilosa Trelease; Curran, Proc. Cal. Acad. 
iT, SSSR EGS: 
A small arborescent shrub with grayish bark and pilose herb- 
age; leaves broadly ovate or nearly orbicular, 15-30 mm. long, 
spinose-serrate ; calyx of staminate flowers 3.6 mm. long, its lobes 
ovate-lanceolate, 1.7 mm. long; anthers 0.5 mm. long, nearly as 
broad ; filaments scarcely dilated at base, nearly twice the length 
of the anthers ; fruiting pedicels equaling the glabrous capsules. 
This species, which was originally collected in the “Santa 
Maria Valley, in the mountains back of San Diego,’’ is apparently 
confined to the San Diego district. It is nearest related to 
Rhamuus ilicifolia, but differs in the pilose herbage, the shorter 
and broader calyx-lobes, and the minute anthers, which are scarcely 
half the size.
