Description
Hyrocotyle umbellata is a perennial terrestrial and aquatic species. The umbrella shaped leaves will dominate groundcover for moist soils or submerged shallow water [1]. The leaves are peltate with veins radiating from the point of the petiole and the blades rounded with heavily notched margins [2]. The star-shaped flowers are small with seperate petals and sepals and five stamen[3].
Distribution
Occurs from south American throughout central American and the Caribbean and along the Atlantic coast[4].
Ecology
Habitat
Hydrocotyle umbellata can occur in swamps, around lakes, shallow water of pond pine flats, sandy peaty ditches, shallow water of flowing streams, moist sands of open flatwoods, and floodplains. It is known to occur in disturbed areas such as roadside ditches, man made ponds, wet pastures, levees, and drainage ditches (FSU Herbarium). Associated species include Eryngium prostratum, Ludwigia arcuata, Panicum hemitomon, and Bacopa (FSU Herbarium).
