Description

edit

Cryptocarya onoprienkoana is a tree that typically grows to a height of up to 35 m (115 ft), its stems buttressed. Its leaves are lance-shaped to elliptic, 80–155 mm (3.1–6.1 in) long and 25–70 mm (1.0–2.8 in) wide, on a petiole 7–19 mm (0.28–0.75 in) long. The flowers creamy green and perfumed, arranged in panicles in leaf axils and are no longer than the leaves. The perianth tube is 0.7–2 mm (0.03–0.08 in) long and 1.3–1.8 mm (0.051–0.071 in) wide. The outer anthers are 0.7–0.9 mm (0.03–0.04 in) long and 0.6–0.8 mm (0.024–0.031 in) wide, the inner anthers 0.7–0.9 mm (0.03–0.04 in) long and 0.5–0.6 mm (0.020–0.024 in) wide. Flowering occurs from September to December, and the fruit is an elliptical, black to bluish-black drupe, 15–22 mm (0.6–0.9 in) long and 11–15 mm (0.43–0.59 in) wide with cream-coloured cotyledons.[2][3]

Taxonomy

edit

Cryptocarya onoprienkoana was first formally described in 1989 by Bernard Hyland in Australian Systematic Botany from specimens collected in 1983.[4]

Distribution and habitat

edit

Rose maple grows in rainforest, sometimes in drier rainforest, at altitudes of 50 to 1,000 m (160 to 3,280 ft) between the Windsor Tablelands in the north and Gympie in central Queensland.[2]
