Description
Mitrephora diversifolia is a tree that typically grows to a height of up to 15 m (49 ft). Its leaves are egg-shaped, 80–300 mm (3.1–11.8 in) long, 30–90 mm (1.2–3.5 in) wide on a petiole 4–6 mm (0.16–0.24 in) long and have 9 to 11 pairs of secondary veins. The flowers are arranged singly in leaf axils on a peduncle up to 15 mm (0.59 in) long, the pedicel 4–6 mm (0.16–0.24 in) long. The sepals are 4 mm (0.16 in) long and densely hairy. Its outer petals cream-coloured, egg-shaped with the narrower end towards the base, 18–22 mm (0.71–0.87 in) long and 13–15 mm (0.51–0.59 in) wide. The inner petals are 5 mm (0.20 in) long and 7 mm (0.28 in) wide, with a mauve-pink, hairy, spade-shaped or arrow-shaped blade. There are 70 to 85 stamens and 10 to 14 carpels each containing 10 ovules. Flowering mostly occurs between October and March, and fruit is egg-shaped, 20–30 mm (0.79–1.18 in) long and 12–20 mm (0.47–0.79 in) wide, containing up to 8 seeds.[3]
Taxonomy
This species was first described in 1841 by Johan Baptist Spanoghe who gave it the name Unona ? diversifolia in the journal Linnaea.[4][5] In 1858, Friedrich Anton Wilhelm Miquel transferred the species to the genus Mitrephora as M. diversifolia. The specific epithet (diversifolia) means "unlike-" or "different-leaved".[6]
Distribution and habitat
Mitrephora diversifolia is native to the Lesser Sunda Islands, Ambon Island in the Maluku Islands, Sulawesi, New Guinea, and northern Queensland.[2]In Queensland it grows in vine forest from the tip of Cape York Peninsula to the McIlwraith Range.[3]
