Flora of the Southeastern United States

Quercus shumardii Buckley. Common name: Shumard Oak. Phenology: Apr; Sep-Oct (of the second year). Habitat: Moist and fertile soils of bottomlands and moist slopes, also in xeric sites over calcareous rocks (such as limestone). Distribution: S. ON, w. NY, sc. PA, west through OH, s. MI, IN, s. IL, MO, and e. KS south to n. peninsular FL and TX.

Origin/Endemic status: Native

Taxonomy Comments: A number of varieties have been recognized in Q. shumardii, and the morphological and habitat variation needs additional study. Var. schneckii (Britton) Sargent is apparently distributed in calcareous uplands west of the Blue Ridge, especially on dry limestone slopes. It is allegedly distinguished by the acorn cups rounded to turbinate below (vs. flattened and saucer-shaped in var. shumardii). Hess & Stoynoff (1998) tentatively concluded that no varieties should be recognized within Q. shumardii. Additional study is needed.
