Description

Acronychia eungellensis is a tree that typically grows to a height of 20 m (66 ft) and has more or less cylindrical stems. The leaves are simple, glabrous and elliptical, 55–90 mm (2.2–3.5 in) long and 20–45 mm (0.79–1.77 in) wide on a petiole 10–20 mm (0.39–0.79 in) long. The flowers are arranged in small to medium-sized groups 20–90 mm (0.79–3.54 in) long, each flower on a pedicel 4–5.5 mm (0.16–0.22 in) long. The four sepals are 1.5–2 mm (0.059–0.079 in) wide, the four petals 6.5–7.5 mm (0.26–0.30 in) long and the eight stamens alternate in length. Flowering occurs in October and the fruit is a fleshy drupe about 12 mm (0.47 in) long and egg-shaped to elliptical in outline.[2][3][4][5]

Taxonomy

Acronychia eungellensis was first formally described in 1982 by Thomas Gordon Hartley and Bernard Hyland in the journal Austrobaileya from specimens collected in the Eungella National Park.[5][6]

Distribution and habitat

This tree grows in rainforest but is restricted to the Eungella National Park and nearby private land at an altitude of about 900 m (3,000 ft) in central-eastern Queensland.[2][3]

Conservation status

Eungella aspen is classified as "near threatened" under the Queensland Government Nature Conservation Act 1992.[2]
