Smith }} 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.[2][3] 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. Eleocharis bifida was described to science in 2001, being separated from the similar Eleocharis compressa. Eleocharis bifida can be recognized by having wider stems and all floral scales bifid (2-lobed).[4]References1. ^{{Cite web | publisher =NatureServe | title = Eleocharis bifida | url = http://www.natureserve.org/explorer/servlet/NatureServe?searchName=Eleocharis+bifida+ | accessdate = 2014-07-07}} {{Taxonbar|from=Q15586197}}2. ^Kew World Checklist of Selected Plant Families 3. ^Biota of North America Program, 2013 county distribution map 4. ^Flora of North America 4 : Eleocharis|Flora of the Eastern United States|Freshwater plants|Plants described in 2001 |
