Taxonomic Notes
Description
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]
Ecology
Habitat
E. melanocarpa is a facultative wetland species found in moist to wet ditches and freshwater pond margins.[5] Such occurrences in these habitats are often ephemeral, sandy, and can range from sunny to shady.[6]
Fire ecology
Despite typically inhabiting wet areas, fires from adjacent habitats (e.g. long-leaf pine savannas, sand-hill pines, Oldfield, 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. [6]
