I am not aware of any toxic chemicals in Anonna glabra (Pond Apple) but do know that D. lindenii is very particular about its growing conditions, ie; 3-5 feet above the high water mark in semi shady locations in the Everglades on the trunks of Pond Apples. I suspect that the texture of the bark has something to do with their success as well as the constant humidity so close to the water. The one that I saw in the Fakahatchee was also covered with moss and lichens around its roots but not blocking the light from the photosynthetic roots.
