Urospatha

Urospatha is a genus of flowering plants in the family Araceae that consists of approximately 10 known species. They are found growing in South America and Central America[2] in swamps, wet savannahs, and brackish water. The leaves of the species in this genus are upward pointing and sagittate (arrow-shaped). The inflorescences are quite unique; the spathe is mottled and elongated with a spiral twist at the end. The seeds are distributed by water and have a texture similar to cork that allows them to float. They also quickly germinate in water.[3][4][5][6]
