''Patersonia'' is a genus of flowering plants in the Iridaceae commonly known as native iris or native flag.〔("Patersonia species" on the australian national herbarium web site )〕 It was first described as a genus in 1807 by Robert Brown. It is native to Australia, New Guinea, New Caledonia, and insular Southeast Asia.〔(Kew World Checklist of Selected Plant Families )〕〔Cooke, D. A. (1986). ''Patersonia''. ''Flora of Australia'' 46: 13-26. Australian Government Publishing Service, Canberra.〕 The genus name is a tribute to the first Lieutenant Governor of New South Wales in Australia, William Paterson. They are perennials with basal leaves growing from a woody rhizome that in some species extends above ground to form a short trunk. The leaves are tough and fibrous, often with adaptations for conserving moisture, such as stomata sunk in grooves, a thickened cross-section, marginal hairs, and thickened margins. The flowers appear from between a pair of bracts on a leafless stem. They have three large outer tepals that are usually blue to violet, and three tiny inner tepals. There are three stamens fused at the base to form a tube around the longer style, which bears a flattened stigma.〔Goldblatt, P. (2011). Systematics of ''Patersonia'' (Iridaceae, Patersonioideae) in the Malesian archipelago. Annals of the Missouri Botanical Garden 98: 514-523.〕 Several ''Patersonia'' species are grown as garden plants. They can be propagated by seed or by division. ;Species〔 # ''Patersonia argyrea'' D.A.Cooke - Gairdner Range in Western Australia # ''Patersonia babianoides'' Benth. - Western Australia # ''Patersonia borneensis'' Stapf - Sabah # ''Patersonia drummondii'' F.Muell. ex Benth. - Western Australia # ''Patersonia fragilis'' (Labill.)
