About Flindersia schottiana F.Muell.
Flindersia schottiana, commonly known as bumpy ash, is a tree that typically reaches a height of 36 meters (118 feet). Its leaves are pinnate, arranged in opposite pairs, and measure 190–400 mm (7.5–15.7 in) long. Most leaves bear ten to sixteen narrow egg-shaped to narrow elliptical leaflets, each 70–160 mm (2.8–6.3 in) long and 15–45 mm (0.59–1.77 in) wide. Side leaflets are more or less sessile, while the end leaflet grows on a petiolule 11–27 mm (0.43–1.06 in) long. Flowers are arranged in panicles 200–270 mm (7.9–10.6 in) long, with five sepals 1–1.5 mm (0.039–0.059 in) long and five white petals 4–6 mm (0.16–0.24 in) long. Flowering takes place from August to December. The fruit is a woody capsule 80–130 mm (3.1–5.1 in) long, with a surface studded with rough points. When mature, the capsule splits into five valves to release winged seeds 50–60 mm (2.0–2.4 in) long. Bumpy ash grows in rainforest habitats ranging from sea level up to an altitude of 800 m (2,600 ft). It occurs in New Guinea, and in Australia from the Claudie River in Kutini-Payamu National Park in far north Queensland to the Hastings River in New South Wales.
