Genus Planchonella Family Sapotaceae

Description: Trees or shrubs, milky latex present, but sometimes sparse. Young shoots often hairy, mostly glabrescent with age.

Leaves often clustered towards ends of branches.

Flowers stalked, solitary or in few-flowered clusters, usually axillary, sometimes ramiflorous. Sepals 5. Petals 5, fused to c. halfway. Stamens 5, staminodes 5 and alternating with the corolla lobes. Ovary mostly 1–6-locular.

Berry 1–6-seeded; seeds narrow-ellipsoid, laterally flattened, usually brown and shiny with a long narrow whitish scar, testa hard and bony.


Distribution and occurrence: World: c. 100 species, mainly Melanesia, Australia, Micronesia–Polynesia, Hawaiian Is., 2 species in South America. Australia: 9 species, Qld, N.S.W., N.T., W.A.

This has sometimes been included in a broad concept of Pouteria, but recent research shows it is distinct (L. Jessup, BRI, pers. comm. 2006 - see Swensen et al. (2007 Cladistics 23: 221-222 and (2007) Taxon 56(2): 337). Not all species have names in Planchonella yet.
