The specimens of C. brevipes in Herb. Gray and the specimen from San 

 Diego County, CaHfornia, have only partly grown fruit, but in the shape of 

 the leaves they so closely resemble the yellow-fruited Arizona trees that there 

 can be little doubt that they are of the same variety, although on the CaU- 

 fornian specimen the leaves are distinctly rough on the upper surface, as they 

 are in the specimen collected by Engelmann and Sargent at Tucson.
