Flowers

Mitrephora diversifolia is a species of flowering plant in the family Annonaceae and is native to Queensland, Ambon Island and New Guinea. It is a tree with egg-shaped leaves, the flowers with cream-coloured and mauve-pink petals, 70 to 85 stamens and 10 to 14 carpels. The fruit is egg-shaped containing up to 8 seeds.

Description[edit]

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 narower 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.[2]

Taxonomy[edit]

This species was first described in 1841 by Johan Baptist Spanoghe who gave it the name Unona ? diversifolia in the journal Linnaea.[3][4] 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".[5]

Distribution and habitat[edit]

Mitrephora diversifolia grows in vine forest from the tip of Cape York Peninsula to the McIlwraith Range and on Ambon Island in Indonesia, and possibly also in New Guinea.[2]
