This widespread northern (circumboreal) species of seasonal wetlands has been collected in BALL (KY) by R. Athey in 1970; in CLIN by Naczi et al. (2002); and recently in BOON and LEWI by R. Cranfill (for NKY). There are also old reports of this species by Britton & Brown (1896), Small (1903), Mackenzie (1931) and others, but these may just be based on C.W. Short's ca. 1840 coll. (NY ex Meisner Herbarium) from "west of Ky.", which cannot be attributed to Ky. Some other loosely allied northern sedges may be expected, especially in section Ceratocystis. Plants from Mich, Ind. and Ohio that were previously known as C. cryptolepis Mackenzie have been recently described as C. viridistellata Derieg, Reznicek, & Bruederle. That species is locally common in Lewis Co. of se. Ohio. Its closest relative, C. lutea, is a narrow endemic in N. Car. (Derieg et al. 2013). These plants superficially suggest depauperate members of section Squarrosae.
