Flindersia australis, commonly known as crow's ash, flindosy or Australian teak,[1] is a species of tree that is endemic to north-eastern Australia. It has pinnate leaves with between five and thirteen egg-shaped to elliptical leaflets, white to cream-coloured flowers arranged in panicles on the ends of branchlets and followed by woody capsules studded with short, rough points and containing winged seeds.
Flindersia australis is a tree that typically grows to a height of, larger trees usually having a buttressed trunk. The leaves are usually arranged alternately and are crowded near the ends of the branchlets. The leaves usually have between five and nine elliptical to egg-shaped leaflets that are long and wide, the side leaflets on a petiolule up to long and the end leaflet on a petiolule sessile or on a petiolule up to long. The flowers are arranged in panicles long and usually include a few male-only flowers. The five sepals are about long and the five petals are white to cream-coloured, long and densely hairy on the back and part of the front. Flowering occurs from September to October and the fruit is a woody capsule long and studded with short, rough points. The seeds are long and winged.[2] [3]
The genus Flindersia and F. australis were first formally described in 1814 by Robert Brown in Matthew Flinders' sea voyage journal A Voyage to Terra Australis, from specimens collected near Broad Sound in September 1802.[4]
Crow's ash grows in rainforest and dry scrub from near Airlie Beach, inland as far as Carnarvon National Park and south to near Kempsey in New South Wales.
Flindersia australis is classified as of "least concern" under the Queensland Government Nature Conservation Act 1992.[5]
