Acronychia suberosa, commonly known as corky acronychia,[2] is a species of small to medium-sized rainforest tree that is endemic to eastern Australia. It has mostly trifoliate leaves with elliptic to egg-shaped leaflets with the narrower end towards the base, small groups of cream-coloured flowers and elliptical to spherical, creamy yellow to whitish fruit.
Description[edit]
Acronychia suberosa is a tree that typically grows to a height of 20 m (66 ft) with a stem diameter of 30 cm (12 in) and a thick, dark crown. The trunk is mostly cylindrical, but occasionally with flanges at the base and the bark is usually smooth, brown or red-brown. The leaves are trifoliate, mostly arranged in opposite pairs, the petiole 10–45 mm (0.39–1.77 in) long, the leaflets elliptical to egg-shaped with the narrower end towards the base, 35–85 mm (1.4–3.3 in) long and 9–30 mm (0.35–1.18 in) wide on a petiolule up to 10 mm (0.39 in) long. The flowers are arranged in cymes 18–35 mm (0.71–1.38 in) long, the individual flowers on a pedicel 1–3.5 mm (0.039–0.138 in) long. The four sepals are 2–3 mm (0.079–0.118 in) wide, the four petals cream-coloured and 6–9 mm (0.24–0.35 in) long and the eight stamens alternate in length. Flowering mainly occurs in February and the fruit is a fleshy, creamy yellow to whitish, elliptical to more or less spherical drupe 12–15 mm (0.47–0.59 in) long. The fruit matures from March to June.[2][3][4]
Taxonomy[edit]
Acronychia suberosa was first formally described in 1932 by Cyril Tenison White in Proceedings of the Royal Society of Queensland from specimens collected in Lamington National Park in 1929.[5][6] The specific epithet suberosa means corky, referring to the bark on older trees.
Distribution and habitat[edit]
Corky acronychia grows from the Richmond River, New South Wales to just over the border at the McPherson Range in south eastern Queensland at altitudes of 200–1,000 m (660–3,280 ft). The habitat is sub-tropical or warm temperate rainforest on basalt soils in high rainfall areas.[2][3][4]
Uses[edit]
Food[edit]
The fruit is edible but acidic.[7]
Horticulture[edit]
Removal of the flesh from the seed is advised for regeneration. Around 30% of the seeds may germinate in five months.[3]
