About

Archidendron lucyi is a small tree in the legume family Fabaceae. The native range extends from eastern Malesia to the Solomon Islands and northeastern Australia. A. lucyi grows in the understorey of lowland rainforest.

As with other members of the genus, A. lucyi produces large pinnate leaves. The species is cauliflorous, producing flowers directly from the trunk. The cream-coloured stamens are 3–5 cm (1.2–2.0 in) long and form the showiest part of the flowers. The flowers are followed by highly conspicuous red or orange seed pods, which split open when ripe to reveal black seeds.
