Flora of the Southeastern United States

Arundinaria alabamensis Triplett. Common name: Tallapoosa Cane. Phenology: Not known to flower. Habitat: Oak-hickory forests and woodlands on mesic, submesic, and xeric slopes and uplands, sometimes occurring as well in hillside seepages, and sometimes along perennial streams (Triplett 2023). Distribution: As far as known, endemic to ec. AL and also in GA piedmont, but expected to have a somewhat wider distribution.

Origin/Endemic status: Endemic

Taxonomy Comments: This species is a stabilized species of hybrid origin between A. gigantea and A. tecta, with closer affinity to A. tecta. "The … analysis suggests that the ancestry of A. alabamensis is more complex than the other sampled species; in general, A. alabamensis appears to harbor more genetic diversity than any of the other sampled species and may derive from two or more ancestral gene pools. This is consistent with a hybrid origin and suggests that A. alabamensis is still in the process of attaining genetic stability or homogeneity. The current data do not provide an estimate of the date of origin of A. alabamensis, but future phylogenomic studies could resolve this question in the broader context of the evolution of the Arundinaria clade of temperate bamboos" (Triplett 2023).
