Description
E. melanocarpa is a perennial, monoecious, graminoid, sedge.[2] On its seed, the tubercle is very short and dilated with its projecting edge rolled over and surrounding the top of the nut.[3] The tips of the culms of E. melanocarpa often arch over and root in the substrate forming a dense tangle. [4] It commonly grows in stools containing several roots and five to 20 stems. Stems range in length from 1 to 3.6 ft (0.3 to 1.1 m) in length. Stools are commonly bunched together into clusters 1 ft (0.3 m) or more in diameter.[3]
Distribution
E. melanocarpa ranges from Massachusetts to Florida and Mississippi, disjunct to eastern Texas, southern Michigan, and northern Indiana. [2][4][1] Despite most studies not listing E. melanocarpa as occurring in Louisiana, the species has been found in parts of Bienville Parish in 2008 suggesting a more connective distribution along its southern range.[5][6]
Ecology
Habitat
E. melanocarpa is a facultative wetland species found in moist to wet ditches and freshwater pond margins,[7] wet pine savannas, and coastal plain bogs.[1] Such occurrences in these habitats are often ephemeral, sandy, and can range from sunny to shady.[5]
Phenology
E. melanocarpa blooms during the months of June and July in more northern parts of its range[8] and in July through September in its southern range.[1]
Fire ecology
Despite typically inhabiting wet areas, fires from adjacent habitats (e.g. longleaf pine savannas, sandhill pines, old-field, etc.) are thought to burn into drawn-down areas of wet ponds/ditches. Such burns likely maintain more open canopy conditions benefiting populations of E. melanocarpa. [5]
Pollination
E. melanocarpa has no organs for attracting insects for pollination. Instead, it relies on the wind to disseminate pollen.[8]
