Quercus Macdonald, var. elegantula Greene, 1. c. 26, 86, t. 29. 
The type of this oak was a tree 20 feet high, with a trunk a 
foot in diameter, discovered by Prof. Greene in 1885, in Temecula 
Cafion near Fallbrook. Asa shrub from 4 to 12 feet high, and 
exhibiting great variation in shape and size of leaf and fruit, it 
is not uncommon from Fallbrook to McGee’s store, near Teme- 
cula. Apparently it is confined to the region jointly occupied 
by QO. Engelmanni and Q. dumosa, between which species it is 
probably a cross, as was suggested by its proposer. 
Quercus chrysolepis Liebm. Spreading but compact tree 40 
feet high, the trunk 2 feet in diameter, or sometimes reduced to a 
shrub. Wood hard and brittle. Cafions of the San Bernardino 
Range, from 1000-5000 feet altitude on the southern slope, and 
from 5000-6000 feet on the northern.
