Morphological Description

Notes: Sandy or rarely gravelly-silty ground, chiefly in uplands; eastern 2/3 of TX; this is the commonest oak species in nc TX and the vegetational dominant in many areas. Post oak tree-ring chronologies extending from about 200 to 300 years have been obtained from North Central Texas sites, with individual trees dating back to 1681 (e.g., Stahle et al. 1985). According to J. Stanford (pers. comm.), hybrids of this species and Q. marilandica can be found in the Lampasas Cut Plain. (stellata: stellate, star-shaped, from the stellate hairs),
