Pichonia

Pichonia is a group of trees in the Sapotaceae described as a genus in 1890.[1][2]

Species are hermaphroditic trees growing to 30 metres tall. Leaves are opposite or subopposite and clustered at the ends of branches. Flowers are cup-shaped or campanulate, grouped in inflorescences, and red or white. The 5–8 corolla tubes are often shorter than the lobes, and the calyx forms of single whorl of five quncuncial sepals. Fruits usually have a single seed.[3]

Pichonia is native to New Caledonia, New Guinea and nearby Islands in Indonesia and Papuasia.[4][5][6] Species grow in rain forests or on rocky and well-drained ridges or slopes at low elevations. The New Caledonia species are restricted to ultramafic soils.[3]
