Leaflet blades about 4.5-9 x 2-8 cm. Midrib raised and often hairy on the upper surface. Leaflet stalk short and swollen at its junction with the compound leaf rhachis.


Inflorescence usually with rusty hairs. Young inflorescence bracts about 3-7 x 1-3 mm. Flowers about 4-5 mm diam. Calyx shortly cupular, lobes five, ovate, subequal, flat, not concave. Fifth petal usually reduced. Disk yellow-orange, +/- horseshoe-shaped. Stamens eight.

Distribution and Ecology

Endemic to Queensland, occurs in CYP and NEQ. Altitudinal range from near sea level to 900 m. Grows in well developed rain forest on a variety of sites but is probably more frequent in drier, more seasonal rain forest.

Natural History & Notes

A commonly cultivated and attractive tree. Produces a dense shady crown and conspicuous crops of yellow fruits with orange arils.

The aril is edible and is sometimes used to make a refreshing drink.
