Planchonella obovata grows as a bushy-crowned tree reaching a maximum height of 10 to 20 metres (33 to 66 ft). The leaves hairy when young, with upper surfaces becoming smooth and shiny. They are roughly oval- to spear-shaped and measure 6–24 cm (2.5–9.5 in) long, and 1.5–15 cm (0.59–5.91 in) wide. Appearing from August to October, the tiny greenish-white flowers grow in clusters. Flowering is followed by round red or blue berries 1–1.5 cm (0.39–0.59 in) in diameter. Each berry contains one to five seeds which are yellow when ripe.[3]
The tree was first described as Sersalisia obovata by Robert Brown in his 1810 work Prodromus Florae Novae Hollandiae.[4] before being moved to its current binomial name Jean Baptiste Louis Pierre in 1890. It is also known by the synonym Pouteria obovata.[1] The specific epithet obovata refers to the reverse ovate shape of the leaf. A genetic analysis of material found that material from Papua New Guinea was isolated and was a sister to a group comprising material from Australia and Indonesia. Indumentum was present on the leaf surface of the Australian and Indonesian samples, and absent in material from Papua New Guinea.[5]
It can be grown in conditions with good drainage with sunny aspect, and can be propagated by seed. The wood is used for turning and cabinet-making.[3]
