Carex lasiocarpa Ehrh.[FNA23, HC, HC2, SPNW]
wiregrass sedge

Publication: Hannover. Mag. 22: 132. 1784.

Origin: Native

selected vouchers: WTU

Notes: FNA23: "Carex lasiocarpa is a dominant of boreal wetlands, often forming huge stands. Large stands of the species are quite striking at a distance because of their pale straw color derived from the dried and faded, curly, filiform leaf apices of the vegetative shoots. Sometimes extensive stands occur without fertile culms.

The reported hybrids between Carex lasiocarpa and C. stricta require confirmation (J. Cayouette and P. M. Catling 1992).

North American plants have, on average, slightly smaller perigynia and shorter beak teeth than European and Asian plants and have been distinguished as subsp. americana (Fernald) Hultén."
