Cyperaceae <Eleocharieae> Eleocharis <Eleogenus> ovata (var. ovata)
Eleocharis ovata (Roth) Roemer & J.A. Schultes
ALI: no HAB: 2,9, ::::, C, 6 ABU: g10?, s9?, -1
This widespread northern (circumboreal) species has been confused with obtusa, and there may be some intergradation (FNA 23, Y). E. ovata differs from obtusa and engelmannii in its relatively narrow tubercles, taller than broad (versus broader than tall), 1/2 to 3/4 as wide as achenes (versus almost as wide), and its stamens only 2 (versus 3). There have been several reports from Ky. (M, FNA 23), but it remains unclear if there are verified colls. from Ky. or elsewhere in the Ohio Valley (PL). No colls. at KY were det. as typical ovata by S.G. Smith for FNA 23.
