Eleocharis uniglumis (Link) J.A. Schultes. Subgenus: Eleocharis. Section: Eleocharis. Series: Eleocharis. Phen: Jul. Hab: Brackish marshes. Dist: NL (Newfoundland) to NC, along the coast; as interpreted broadly (including E. halophila) E. uniglumis also occurs in Eurasia.

Origin/Endemic status: Native

Taxonomy Comments: Crow and Hellquist (2000) recognized Eleocharis halophila as distinct from E. uniglumis by having thinner tubercles (0.2-0.5 mm vs. 0.6-1 mm); thus, being longer than wide (vs. about as wide as long in E. uniglumis). Smith et al. (2002) placed E. halophila under synonymy with E. uniglumis, primarily due to intermediacy in characters, but mention that it has narrower, more densely arranged floral scales, and tends to occur in Atlantic Coastal brackish habitats. Smith also stated that the achene and tubercle characters mentioned by Fernald (1950) are invalid. We recognize a broader, more widely distributed E. uniglumis, despite the number of various taxa published.
