Acronychia acronychioides, commonly known as white aspen,[2] is a species of small to medium-sized rainforest tree that is endemic to north-eastern Queensland. It has trifoliate leaves with elliptic to egg-shaped leaflets on stems that are more or less cylindrical, creamy yellow flowers in large groups in leaf axils and fleshy, pear-shaped or spherical fruit.
Acronychia acronychioides is a tree that typically grows to a height of 25 m (82 ft) and has more or less cylindrical stems. The leaves are usually trifoliate on a petiole 20–80 mm (0.79–3.15 in) long. The leaflets are elliptic to egg-shaped with the narrower end towards the base, 70–210 mm (2.8–8.3 in) long and 20–65 mm (0.79–2.56 in) wide on a petiolule up to 8 mm (0.31 in) long. The flowers are arranged in large groups 30–100 mm (1.2–3.9 in) long in leaf axils, each flower on a pedicel 3–7.5 mm (0.12–0.30 in) long. The four sepals are 2–3 mm (0.079–0.118 in) wide, the four petals 8–10 mm (0.31–0.39 in) long and the eight stamens alternate in length. Flowering occurs from April to May and the fruit is a fleshy, pear-shaped to spherical drupe 8–13 mm (0.31–0.51 in) long.[2][3]
Taxonomy
White aspen was first formally described in 1864 by Ferdinand von Mueller who gave it the name Euodia acronychioides and published the description in Fragmenta phytographiae Australiae.[4][5] In 1974, Thomas Gordon Hartley changed the name to Acronychia acronychioides in the Journal of the Arnold Arboretum.[6][7]
