Leaves variable, adult leaves narrow-elliptic to elliptic, tapering at both ends, 80–115 mm long, 20–30 mm wide, margins undulate, crenulate, apices acute to barely acuminate in adult leaves; adaxial (upper) surface with venation becoming more impressed with age; abaxial surface smooth; petioles 15–25 mm long. Inflorescences shortly pedunculate, triads to branched umbels, elongating by anthesis but still barely exceeding the surrounding leaves; rachis Flowers urceolate-salverform; pedicels
A tall shrub or small tree. It grows up to 20 m tall. Sometimes it is only 3-4 m tall. The branches have rusty hairs. The leaves are 25 cm long by 8 cm wide. They are alternate and sword shaped. They are dark green above and with rusty hairs underneath. Flowers are about 0.8 cm across. They are white or creamy yellow. They occur in groups at the ends of branches. The flower petals are 6-7 mm long. The fruit is a 3-valve capsule. It is tiny and the fruit is a dull yellow. The fruit is about 1.5 cm across. The seeds are right red and sticky.
Common small tree or shrub in the tropical and montane zones, near the seashore (edge of swamps, rocks, etc.), along rivers, in dry bushes, on steppes and in open savannah land, sometimes as undergrowth in rain-forests or in secondary forests from the lowland up to 1800 m, in New Guinea once at 2800 m.

Edges of swamps, rocks, etc along the seashore; along rivers; in dry bushes; on steppes; in open savannah land; sometimes as undergrowth in rain-forests or secondary forests; at elevations up to 1,800 metres.
It is a tropical plant. It suits seasonally dry areas. It does best in shade. It needs well drained soils. It grows in vine forests and on the edges of rainforests.
In Malesia, known to occur on calcareous soils (Blume 1826); in Australia, coastal but not known from coral soils.
