Eleocharis bifida

About

Eleocharis bifida is a species of spikesedge known by the common name glade spikerush. It is native to the Eastern United States, where it is endemic to the Interior Low Plateau and very small part of the Ridge and Valley ecoregions. This is mostly in Kentucky and Tennessee, extending into southern Indiana, northern Alabama, and northwestern Georgia. It is found only in wet areas in cedar glades, such as pools and streamsides. This narrow habitat requirement is the reason for it being considered vulnerable.
