About

Planchonella obovata is a species of tree in the family Sapotaceae. The common name in Australia is the northern yellow boxwood. It occurs in many parts of south-east Asia, Micronesia, and on islands of the Indian Ocean, and has local common names there.

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.
