This semi-deciduous tree sheds some of its leaves. Its branches spread to form an open crown. Reported heights range from 33–98 feet [10–30 metres]. Poor growing conditions can keep trees smaller. Some reports record trees reaching 131 feet [40 metres]. The straight, round trunk can reach about 5 feet [1.5 metres] across. Bees pollinate its flowers. Its bark releases a red resin rich in tannins. People use this resin as a dye.
