Carex louisianica, commonly called Louisiana sedge, is a species of flowering plant in the sedge family. It is native to North America, where it is primarily found in the southeastern United States. Its natural habitat is wet, swampy forests and openings.Flora of North America It is a rhizomatous perennial that flowers in spring. It produces fruits in late spring and summer.

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
