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). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
As with many of the Madrean counterparts of the oak flora, in very dry years trees progressively lose their leaves through the long dry spring and may become virtually leafless by the time the rains come in early summer (R. W. Spellenberg, pers. comm.). In the flora, Quercus viminea is known from a single sterile specimen collected at Red Mountain, Santa Cruz County, Arizona. Recent attempts to find the taxon at this site have been fruitless. The Arizona specimen is similar to specimens from northern Mexico that have small, usually entire, narrowly lanceolate leaves with short petioles. These northern forms appear to grade clinally into larger-leaved southern forms that fit the general description of Q. bolanyosensis Trelease.
