Sesbania formosa (common names - White dragon tree, Vegetable humming bird, Swamp corkwood; Dragon tree; Dragon flower tree)[1] is a leguminous tree native to northern Australia, first described in 1860 by Ferdinand von Mueller as Agati formosum, from specimens collected the banks of the Victoria and Fitzmaurice Rivers.[2] It was transferred to the genus, Sesbania, by Nancy Burbidge in 1965.
It is native to Western Australia and the Northern Territory,[3] and grows in tropical wetlands,[4] to heights of 20 to 30 feet, in closed forests or swampy sites, from sea level to 100 m.
