China pine

About

Goniothalamus australis, commonly known as China pine, is a species of plants in the custard apple family Annonaceae found only in the Wet Tropics bioregion of Queensland, Australia. It is a tree normally reaching about 20 m (66 ft) and 15 cm (5.9 in) diameter, but may reach 30 m (98 ft) on occasions. The leaves may reach up to 12 cm (4.7 in) long and 5 cm (2.0 in) wide, with 9–12 pairs of lateral veins on either side of the midrib. Flowers are solitary or (rarely) paired, with 3 sepals and 6 petals in two whorls of 3. The inner petals are much smaller than the outer ones and they are joined laterally, forming a cap over the reproductive organs. Stamens number about 80, ovaries number about 10 with up to 8 ovules each. Fruit are up to 6 cm (2.4 in) long by 2.5 cm (0.98 in) wide and contain up to 6 seeds. The species was first described by Laurence W. Jessup in 1986. It grows in upland rainforest at altitudes from 600 to 1,200 m, on the Atherton Tableland and northward to about Cooktown.
