Concept Reference

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: Isoetes engelmannii
Taxonomic Comments: As treated by Kartesz (1999), excludes var. caroliniana (treated as Isoetes valida, with synonym I. caroliniana). GRANK 'G4' received from M. Penskar and A. Reznicek (1992). Kartesz (1994) had included Isoetes engelmannii var. valida in I. engelmannii, but Brunton and Britton (1996) recognized it as a distinct, full species (I. valida) which includes I. caroliniana.

Committee on the Status of Endangered Wildlife in Canada (COSEWIC): Endangered (01May2001)
Comments on COSEWIC: Reason for designation: Few highly restricted populations in Ontario occurring in two rivers, disjunct from the core range of the species in the northeastern United States, and at risk from recreational boating activities, loss in water quality and possible impact of zebra mussels.

Status history: Designated Endangered in April 1992. Status re-examined and confirmed in May 2001.
