Qucrcus Macdonaldi, var. clcgantula Greene, 1. c. 26, 86, t. 29. 

 The type of this oak was a tree 20 feet bigh, with a trunk a 

 foot in diameter, discovered by Prof. Greene in 1885, i'^ Temecula 

 Canon near Fallbrook. As a 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 0. Engclmanni and Q. diunosa, between which species it is 

 probably a cross, as was suggested by its proposer.
