Carex communis L.H. Bailey. Section: [26bbb] Section 39 Acrocystis. Phen: May-Jun. Hab: Dry woodlands and forests, bluffs, rich forests, streambanks. Dist: PE west to MN, south to n. SC, c. GA (Jones & Coile 1988), and AR.
Origin/Endemic status: Native
Taxonomy Comments: Carex amplisquama F.J. Hermann was originally described to include plants with longer beak teeth and pistillate scales than typical C. communis. Despite considerable cytogenetic and morphological variation with this species, current molecular sampling across its range does not reveal significant patterns that would justify taxonomic recognition of segregate taxa. Additional study is needed.
