Burao is found in the tropics and subtropics and is native to Vanuatu.
An evergreen tree, it can grow to 3-10 m in height. It has a crooked, tangled and sprawling shape and the canopy is generally wider than its height. The bark is smooth to lightly fissured and grey to light brown in colour. The bark thickens and roughens as the tree ages.
Burao can be highly variable in shape and in the leaf and flower colours.
The leaves are 6-22 cm in length and have an ovate (oval or egg shaped) to orbicular shape (spherical or rounded). They can be heart-shaped and are large and wavy. The upper surface of the leaves is bright green and greyish-green and hairy on the underside.
Terminal 3-6 flowered cymes (flower cluster with a central stem where a single terminal flower develops before the others develop off lateral stems) or solitary. Five radiating, obovate (ovate with a narrower end at the base), yellow petals that are 4-6.5 cm long and have a base colour of dark red/maroon. The stamen, or male fertilizing organ of the flower, has a tube that is 2-2.5 cm in length. The flowers are showy, fragile, and short-lived, falling the same day that they open. The flowers fade to pink prior to falling.
The fruits are 1.6 to 2.2 cm in length. The fruit casing is ovoid-ellipsoid in shape and light brown in colour with densely matted grey woolly hairs.
The seeds are brown, 4 x 2 mm in length and width, tuberculate (kidney-shaped, with 5-7 seeds per cell), and hairy.
