Vaccinium pallidum Aiton. Hillside Blueberry, Dryland Blueberry. Phen: Mar-Apr; Jun-Jul. Hab: Forested slopes, usually rather xeric. Dist: Widespread in e. United States, V. pallidum is centered in the Appalachians and Ozarks.

Origin/Endemic status: Native

Taxonomy Comments: Vander Kloet (1978, 1988) and Uttal (1987) do not favor Camp's (1945) separation of V. pallidum and V. vacillans. If the two taxa are combined (as here), V. pallidum has nomenclatural priority. V. pallidum is primarily diploid; Redpath et al. (2022) report diploid and tetraploid counts for V. pallidum, but the tetraploid counts likely are based on what is here treated as a separate species, V. altomontanum. See V. altomontanum for discussion of its relationship to V. pallidum.
