Alphitonia is a genus of arborescent flowering plants comprising about 20 species, constituting part of the buckthorn family (Rhamnaceae). They occur in tropical regions of Southeast Asia, Oceania and Polynesia. These are large trees or shrubs. In Australia, they are often called "ash trees" or "sarsaparilla trees". This is rather misleading however; among the flowering plants, Alphitonia is not closely related to the true ash trees, and barely at all to the monocot sarsaparilla vines (Smilax).
Annona glabra is a tropical fruit tree in the family Annonaceae, in the same genus as the soursop and cherimoya.

The A. glabra tree is considered an invasive species in Sri Lanka and Australia. It grows in swamps, is tolerant of saltwater, and cannot grow in dry soil.
