Nearly worldwide, tropics and subtropics.
Discussion
Genera 17, species ca. 120 (1 in the flora).
Bruguiera gymnorrhiza (Linnaeus) Savigny (large-leafed orange mangrove), native to the Indian and western Pacific Islands, has been found as an escape in Miami-Dade County, Florida. It is considered invasive in Florida and efforts are underway to eradicate it. Bruguiera may be distinguished from Rhizophora by its 8–16 sepals and petals and lack of aerial stilt roots.
