Habitat
Habitats of E. decangulare var. decangulare include wet pine flatwoods and savannas, mafic fens and seeps, bogs, wind-tidal marshes, and seasonally flooded pools. As well, E. decangulare var. latifolium can be found in seepage bogs.[3] E. decangulare has been observed in a range of habitats including pond edges, in standing water of shallow ponds, moist depressions, bog muck, peaty margins, old stump hole depressions in savannas, sphagnous bogs, swampy areas, inundated pineland glades, and interdunal flats. Soils include sandy and wet soils, muck, moist to wet sandy peat, and rich loamy sand.[4] The species is listed by the USDA Natural Resources Conservation Service as an obligate wetland species that is almost exclusively found in wetland habitats.[2] It requires full sun, and has a low tolerance for calcium carbonate.[1]
