Concept Reference: Kartesz, J.T. 1994. A synonymized checklist of the vascular flora of the United States, Canada, and Greenland. 2nd edition. 2 vols. Timber Press, Portland, OR.
Concept Reference Code: B94KAR01HQUS
Name Used in Concept Reference: Eleocharis engelmannii
Taxonomic Comments: Eleocharis engelmannii is part of one of the most taxonomically challenging complexes in the genus (Yatskievych 1999). E. engelmanii is recognized as distinct by Kartesz (1999) and others (Voss 1972, Great Plains Flora Association 1986). However, some authors have treated the complex as one species (with no infraspecific taxa) (Gleason and Cronquist 1991, Moss 1994, Yatskievych 1999).

NatureServe Status

Global Status: G4G5
Global Status Last Reviewed: 29Aug2002
Global Status Last Changed: 04Sep2002
Rounded Global Status: G4 - Apparently Secure
Reasons: Eleocharis engelmanni seems to be widespread and relatively common through much of its range, although it is rare in Canada and the Great Lakes states and historical in Maine and West Virginia. However, because it is very difficult to distinguish from closely related taxa and sometimes lumped with these other taxa it is not possible to confirm its exact status.
