Eleocharis tenuis (Willdenow) J.A. Schultes var. pseudoptera (Weatherby ex Svenson) Svenson. Phen: Jun-Sep. Hab: Bogs, seepages, margins of wooded swamps. Dist: NS, QC and IN south to NC and nw. GA; disjunct in s. IL.

Origin/Endemic status: Native

Taxonomy Comments: See Gibbons & McMullen (2019) for detailed discussion of the E. tenuis complex. This variety may warrant species rank status, distinct from E. tenuis (var. tenuis), as it sometimes co-occurs and remains morphologically distinct. A single collection from Murray County, GA (Morton 43373) has been verified at APSC and NCU by S. Galen Smith and Scott Ward, respectively.
