Eleocharis flavescens var. olivacea (Torr.) Gleason: is found along shorelines in eastern North America along the Atlantic coast and inland south of the Great Lakes to Minnesota.[2] It is a short caespitose plant with biconvex, green to dark brown, achenes.[2] The achenes have a two-cleft style and bristles that are as long or longer than the achene.[2] The scales of the achene are rounded with round tips and have a green midrib.[2] In Minnesota it reaches its most westerly distribution and it is listed as a Threatened species because of its rarity.[3] It is a wetland species found in only a few locations in Minnesota but this may be due to under collecting because the species is small and looks like other species. In Minnesota, it has been found growing on a mucky lakeshore in a mixed forest, and along a muddy shoreline of a peat pond.[2]
Eleocharis flavescens var. flavescens: with red-brown to dark brown ripe achenes.[1] It grows in southern and western USA, the West Indies, and South America.[1]
