Discussion

Quercus pagoda is often treated as a variety of Q. falcata; it is quite distinctive, however, both morphologically and ecologically (S. A. Ware 1967; R. J. Jensen 1989).

This species reportedly hybridizes with Q. falcata and Q. phellos (D. M. Hunt 1989).

The name Quercus dumosa (see species treatment no. 72) has often been applied to this species.

Quercus berberidifolia is the most common scrub oak of central and southern California, mostly at midelevations in the Coast Ranges. In central California it is replaced in drier interior habitats by Q. john-tuckeri, and south of the transverse ranges by Q. cornelius-mulleri. From Santa Barbara south, it does not descend to the low elevation coastal sites typical of Q. dumosa in the strict sense. Quercus berberidifolia hybridizes with numerous other white oaks of California. In southern California, putative hybrids with Q. john-tuckeri are noticeable in the mountains above Ventura and on the north slope of the Tehachapi Mountains.
