The leaves are shallowly tri-lobed, glaucous beneath and deeply peltate. The twig is solid and thus does not house ants. Stipules are light green in colour, papery, huge, hairly and erect. The fruits are 4–5 by 6–8 mm wide and 2-shouldered.

Macaranga gigantea has broad ecological range from lowland coastal forests to swampy forests up til 1000 m. It is one of the earliest colonisers of degraded land but it is also found in large gaps in primary forests. This tree has been found to be dominant 20–30 years after shifting cultivation.
It produces huge quantities of seeds eaten that are eaten by small birds and squirrels.
