  • Comment: "Oryza nivara is part of the O. sativa complex and is related to O. rufipogon and O. meridionalis (In the AA genome group of wild rice). It was reported to occur in Australia in the N.T. by S.D.Sharma & S.V.S.Shastry, op. cit. 165 [Indian Journal of Genetics and Plant Breeding 25: 161, figs 2, 3 (1965)]. The basis for this cited N.T. distribution is unknown, however there is also a record from Qld based on Clarkson 7320 (BRI, K, L, NSW) ( D.A.Vaughan & B.K.Simon, pers. comm.). This specimen, and others similar to it, has been treated as O. meridionalis in Australian herbaria and is difficult to distinguish from O. nivara. The status and placement of O. nivara is uncertain, especially in the Australian context where specimens appear to be difficult to distinguish from other AA genome Oryza species. The holotype has not been seen to enable further assessment. there may be introduced AA genome wild rice from Asia (brought in by birds or humans) in Australia and there appear to be intermediates and the possibility for hybrids that would complicate the current understanding of the taxa present (e.g. status of O. nivara), and the complex warrants detailed study (D.A.Vaughan, pers. comm.). Further notes on these issues are provided by P.G.Kodela, Telopea 12(3) (in press) [being 443-444 (2009)]."
