Eleocharis xyridiformis Fernald & Brackett. Subgenus: Eleocharis. Section: Eleocharis. Series: Eleocharis.

Origin/Endemic status: Sw. North America
Other Comments: See the discussion under Eleocharis macrostachya [Variant a] in Smith et al. (2002), for which the provisional acceptance here is based. Further clarification is also needed for variant B (here recognized as a finer concept of E. macrostachya) and the 4 variants described under Eleocharis palustris. Plants trending towards E. macrostachya in the far western portions of the flora should consider this taxon, although it may not be as broadly distributed.
