Carex atlantica L.H. Bailey. Section: [26o] Section 11 Stellulatae. Prickly Bog Sedge. Phen: May-Jun. Hab: Bogs and seepages. Dist: NS west to MI and nw. IN, south to ne. FL, Panhandle FL, and e. TX.

Origin/Endemic status: Native

Taxonomy Comments: Reznicek & Ball (1980) found the distinction of C. incomperta from C. atlantica to be untenable. Intermediates between C. atlantica and C. howei (often treated as C. atlantica ssp. capillacea) occur in portions of their ranges, especially in the southern Coastal Plain. In most other areas they are sharply distinct, and sometimes grow together (as in the mountains of our area and farther north) with no evidence of intergradation or hybridization. I prefer to treat them at the species level.
