About Pentaceras australe (F.Muell.) Hook.fil.
Pentaceras australe (F.Muell.) Hook.fil. is a tree that typically reaches a height of 27 metres (89 feet), with a diameter at breast height of 45 centimetres (18 inches). Its bark is smooth, coloured grey-fawn, marked with small horizontal lines, and develops flanges at the base on larger trees. The leaves are pinnate, ranging from 150 to 500 millimetres (5.9 to 19.7 inches) long, and bear between five and fifteen leaflets. Leaflets are shaped egg-shaped to lance-shaped, measuring 50 to 130 millimetres (2.0 to 5.1 inches) long and 7 to 65 millimetres (0.28 to 2.56 inches) wide. Lateral leaflets are either sessile or attached by a petiolule up to 9 millimetres (0.35 inches) long, while the terminal leaflet sits on a petiolule 7 to 35 millimetres (0.28 to 1.38 inches) long. Flowers are around 6 millimetres (0.24 inches) in diameter, arranged in fragrant panicles 120 to 350 millimetres (4.7 to 13.8 inches) long. Sepals are 0.6 to 1 millimetre (0.024 to 0.039 inches) long, and petals are white and 2.5 to 3 millimetres (0.098 to 0.118 inches) long. Flowering takes place from June to October. The fruit is a samara 20 to 45 millimetres (0.79 to 1.77 inches) long, with a seed around 3 millimetres (0.12 inches) long. This species grows in rainforest, most commonly dry rainforest, at altitudes from near sea level up to 900 metres (3,000 feet). It occurs from near Gympie in Queensland to near Stroud in New South Wales.
