180. Evpnorpracea ?—A shrub found on the coast from San Quentin to the Bay of Magdalena, 
always close to the sea, with opposite, coriaceous, entire, ovate leaves, and small heads of flowers on 
very short peduncles, which may possibly belong to the Luphorbiacee, but the flowers on the 
specimens found are all male, and only in very young bud.

JULIFLORA. 
182—186. Sauices.—There are in the collection specimens of five species of willow, all from 
San Francisco, and all Spparently different from any North American species I am acquainted with; 
but sd they are in leaf only, it is useless to attempt to describe them so as to be afterwards
