This fast-growing tree typically reaches 15 meters tall, though it can reach 25 meters in some habitats.[3] The star-shaped yellow flowers give way to dry capsules covered with soft green spines.[4] The leaves are pointed at the tip and rounded at the base, 10–30 centimeters long and 6–12 centimeters wide, borne on petioles 1–3 centimeters long.[5] The leaf margins are lightly serrated, and the veins are lightly hairy.[6]
The wood is light and floats easily, so it is used to make buoys and small boats.[7]
