Flora of the Southeastern United States

Quercus muehlenbergii Engelmann. Common name: Yellow Oak, Chinquapin Oak. Phenology: Apr-May; Oct-Nov (of the same year). Habitat: Slopes and bluffs, on soils derived from calcareous or mafic rocks. Distribution: S. New England and ON west to WI, se. MN, and IA, south to nw. FL, TX, and n. Mexico (CHH, COA, NLE, SON, TAM).

ID notes: The similar Q. montana sometimes has a few leaves with somewhat sharply lobed leaves, but these are minutely mucronate and lack the well-developed callus of Q. muehlenbergii. Additionally, Q. muehlenbergii has a flaky, light gray bark, very different from the dark gray, deeply furrowed bark of Q. montana.

Origin/Endemic status: Native

Taxonomy Comments: The species was originally named as "Quercus mühlenbergii", which must be corrected under the Shenzhen Code to ‘muehlenbergii’.
