Alsomitra is a genus of 34 species of vines found in Southeast Asia, Australia and South America. The fruits or pepos are football-sized (about 300mm diameter) and bell-shaped, suspended high in the forest canopy, and are densely packed with large numbers of seeds. Remarkably the seeds have large, papery wings and when ripe they fall from the underside of the fruit and glide long distances.http://www.bambus.de/forum/66641.html?dar_start=300 The plant was first described under the name Zanonia macrocarpa in 1825 by Carl Ludwig Blume from fruiting material collected on Mount Parang in Java.
