The species grows as a monoecious tree to 35 m in height, with a bole of up to 5 m. The smooth oval to lance-shaped leaves are 12–30 cm long by 6–17 cm wide. The inflorescences occur in the leaf axils. The fruits are infructescent, olive to brown in colour, 8–12 cm by 7–8 cm in diameter, containing seeds covered by an edible, sweet and juicy aril.[1]
Variety
The variety endemic to north-eastern Borneo, sometimes considered a subspecies A. l. clementis, differs in having somewhat more lanceolate leaves, and the fruits having an orange (rather than white) aril.[1]
