Celtis pumila Pursh. Common name: Dwarf Hackberry, Georgia Hackberry. Phenology: Apr-May; Aug-Oct. Habitat: Xeric to mesic glades, outcrops, barrens, woodlands, exposed bluffs, stream banks, and disturbed areas, often over calcareous substrate. Distribution: NJ, PA, IN, IL, and KS south to Panhandle FL and TX.
Origin/Endemic status: Native
Taxonomy Comments: C. pumila Pursh has priority over C. tenuifolia Nuttall; the description in Pursh's flora ("a small straggling bush"), and more critically the type specimen, conform to what has more generally been known as C. tenuifolia (Whittemore in Yatskievych 2013). This species is mainly an apomictic triploid.
