Description

[edit]

Engelhardia rigida grows up to 50 m (160 ft) tall, with a trunk diameter of up to 90 cm (40 in). It has buttresses up to 3 m (10 ft) high and extending out to 2 m (7 ft). The bark is reddish to grey. The papery leaves are elliptic to ovate and measure up to 7.1 cm (2.8 in) long, occasionally to 16.5 cm (6.5 in) long. The fruits are winged.[3] The tree is sometimes harvested for its timber in Papua New Guinea.[1]

Distribution and habitat

[edit]

Engelhardia rigida is native to Borneo, Java, Sulawesi, the Maluku Islands, the Philippines and New Guinea. Its habitat is mixed dipterocarp forests, to elevations of 2,500 m (8,000 ft). It is threatened by conversion of its habitat for urban development and agriculture.[1]
