What is "medusagyne"

Medusagyne oppositifolia, the jellyfish tree, is a critically endangered and unusual tree endemic to the island of Mahé, of the Seychelles. It is the only member of the Medusagyne genus of the Ochnaceae family of tropical trees and shrubs. The plant, thought to be extinct until a few individuals were found in the 1970s, gets its common name from the distinctive jellyfish-like shape of its dehisced fruit.
