Description
editCryptocarya gregsonii is a small tree that typically grows to a height of up to 12 m (39 ft). The leaves are thick and leathery, egg-shaped to more or less round or elliptic, 30–80 mm (1.2–3.1 in) long and up to 55 mm (2.2 in) wide. The flowers are green, small in number, about 5 mm (0.20 in) in diameter, borne in the axils of upper leaves. Flowering occurs from November to February and the fruit is a black, fleshy, elliptic to oval drupe, 40–60 mm (1.6–2.4 in) long, 35–40 mm (1.4–1.6 in) wide and about 25 mm (0.98 in) thick.[2]
Taxonomy
editCryptocarya gregsonii was first formally described in 1902 by Joseph Maiden in the Proceedings of the Linnean Society of New South Wales.[3][4] It was named by Maiden after his friend Jesse Gregson of Newcastle.[2][4]
Distribution and habitat
editNative blackbutt is endemic to Lord Howe Island where it prefers moist, sheltered areas. It is ocally abundant in the southern mountains of the island, from an altitude of 300 m (980 ft) to the summit of Mount Gower at 875 m (2,871 ft).[2]
