Carex lupuliformis
Species of grass-like plant
Carex lupuliformis, common name false hop sedge,[1] is a perennial sedge of sporadic distribution found in the floodplain forests and ephemeral woodland ponds[2] of central and eastern North America. The species typically produces four to seven leaves with sheaths of distal leaves of 3 to 21 cm whose ligules are rounded to triangular.[2] Carex lupuliformis blooms between early June and early October, typically with "two to six proximal female spikes, distal spikes usually crowded, ascending, densely flowered, usually cylindric, much longer than broad; one to two terminal male spikes."[2] Fruiting occurs between late July through early October. Fruit is described as "perigynia ascending to spreading, inflated, strongly veined, sessile, lance-ovoid, shiny, glabrous; beak conical; achenes stipitate, broadly diamond-shaped, scarcely if at all longer than wide, concave faces, angles thickened, prominently knobbed with hard, nipplelike points."[2]
