Zygogynum Explained
Zygogynum is a genus of plant in the winter's bark family Winteraceae. 19 species are native to New Caledonia, and are pollinated primarily by beetles and moths.[1] Other species are native to New Guinea (21 species), the Bismarck Archipelago (1 species), the Solomon Islands (2 species), Lord Howe Island (1 species), and Queensland (2 species).[2]
This genus is interesting for having the greatest range in the number of stamens in any genus: as few as three or as many as 370; a 123 fold difference in the number of stamens. The number of carpels can range from one to as many as fifty.[3]
