Australian Citreae with notes on other Aurantioideae (Rutaceae)

Australian Citreae with notes on other Aurantioideae (Rutaceae).Telopea 7(4): [333][334][335][336][337][338][339][340][341][342][343][344].Both subtribes of tribe Citreae (Rutaceae: subfam.Aurantioideae) are represented in Australia: the sole representative of 'Triphasiinae' is here referred to Luvunga Wight & Arn., in which the new combination, L. monophylla (D.C.) Mabb., is proposed, and the relationships of the Australian Citrineae to the genus Citrus L. are reassessed; Eremocitrus Swingle and Microcitrus Swingle are reunited with Citrus.A new species, C. gracilis Mabb.from the Northern Territory, is described and a conspectus of, and an identification key to, Australian native Citrus spp.presented; 'Sydney Hybrid' is formally described and named C. × virgata Mabb.; a new combination, C. × floridana (J.Ingram & H. Moore) Mabb., for the name of the limequat and a new name, C. wintersii Mabb., for one of the Papuan endemic species formerly referred to Microcitrus are proposed.In tribe Clauseneae, notes on Glycosmis, Micromelum and Murraya, especially on typification of names , are presented. Rutaceae: Aurantioideae in AustraliaThis paper is a prelude to the account of the subfamily Aurantioideae Horan.for Flora of Australia, in which full descriptions will be found, so those are not repeated here.The subfamily in its wild state is restricted to the tropics and subtemperate parts of the Old World and comprises two tribes: Clauseneae Wight & Arn. and Citreae Meissner, both of which are represented in Australia.Native Clauseneae are species of Clausena Burm.f., Glycosmis Correa, Micromelum Blume and Murraya L. (see Appendix); Citreae are represented by species referred to two of the three subtribes recognised by Swingle (1944: 136-7), viz.Triphasiinae Swingle (apparently not validly published) and Citrineae Engl.It is worth noting here that the traditionally used subfamily name for this assemblage was validly published in 1847 (I am greatly indebted to Jim Reveal for pointing this out): Rutaceae Juss.subfam.Aurantioideae Horan., Char.
