About Guioa acutifolia Radlk.
Guioa acutifolia (common names: glossy tamarind, northern guioa, and sharp-leaf guioa) is an evergreen tree native to New Guinea and the coastal areas of eastern Queensland, Australia. This species grows up to 20 metres tall, with a trunk that may reach 15 cm wide and bears smooth grey bark. In its native range, sweetly scented flowers develop between August and October. Both flowers and fruits often grow on immature trees. It was formally described in 1879 by Bavarian botanist Ludwig Radlkofer. Radlkofer’s name may have been based on an earlier description by Ferdinand von Mueller of an acute-leaved variety of Cupania semiglauca, but this earlier description did not include a formal varietal name. Mueller’s description was based on plant material collected from Port Denison, Rockingham Bay, and the Mossman River. Guioa acutifolia grows on beaches, among mangroves, and at higher altitudes along creeks in the understorey of rainforest edges. In Australia, its distribution stretches from Cape York south to Fraser Island. It can be propagated from seed, and requires partial shade until it becomes established.
