Cunoniaceae is a family of 27 genera and about 335 species of woody plants in the order Oxalidales, mostly found in the tropical and wet temperate regions of the Southern Hemisphere. The greatest diversity of genera are in Australia and Tasmania, New Guinea, and New Caledonia. The family is also present in Central America, South America, the Caribbean, Malesia, the islands of the South Pacific, Madagascar and surrounding islands. The family is absent from mainland Asia except from Peninsular Malaysia, and almost absent from mainland Africa apart from two species from Southern Africa. Several of the genera have remarkable disjunct ranges, found on more than one continent, e.g. Cunonia, Eucryphia Weinmannia.

Researchers in Chile built a large, high-quality image library of 16 pollen types from the Biobío Region, complete with precise shape outlines verified by a pollen expert. This dataset is designed to train AI systems that can automatically identify pollen — a task that matters for tracking plant diversity, allergies, and honey authenticity.
