The same systems are used to arrange the botanical collections of the Tasmanian Herbarium and by the Flora of Australia series published by the Australian Biological Resources Study (ABRS). For a more up-to-date classification of the flora, refer to The Flora of Tasmania Online (Duretto 2009+) which currently follows APG II (2003). To determine the families in which genera are placed, refer to Appendix 2 at the end of this document. This census also serves as an index to The Student’s Flora of Tasmania (Curtis 1963, 1967, 1979; Curtis & Morris 1975, 1994). Species accounts can be found in The Student’s Flora of Tasmania by referring to the volume and page number reference that is given in the far right column (e.g. 3:539). Families with accounts completed in the Flora of Tasmania Online (Duretto 2009+) are highlighted at the family entry (e.g. FTO 1). The Census of the Vascular Plants of Tasmania incorporates every name (including synonyms) used to refer to Tasmanian plants in the major taxonomic publications about Tasmania, and tries to account for every species name attributed to Tasmania, whether erroneously or correctly. Names from the following publications have been included: Jacques-Julien Houtou de Labillardière’s Novae Hollandiae Plantarum Specimen (1804-1807), Robert Brown’s Prodromus Florae Novae Hollandiae et Insulae van-Diemen (1810), Joseph Dalton Hooker’s The Botany of the Antarctic Voyage of H. M. Discovery Ships Erebus and Terror in the Years 1839 - 1843 Under the Command of Captain Sir James Clark Ross. Part III: Flora Tasmaniae (1855-1859, complete work published in 1860), all volumes of George Bentham’s Flora Australiensis (1863-1878) and Leonard Rodway’s The Tasmanian Flora (1903). In addition, all names used in Cheeseman’s (1919) The Vascular Flora of Macquarie Island have been accounted for in the Macquarie Island section. According to this Census, the Tasmanian flora contains 2719 vascular plants, of which 1918 (70%) are considered native and 801 (30%) have naturalised from elsewhere. Among the native taxa, 530 (28%) are endemic to the State. Thirty-seven of the State’s exotic taxa, are considered sparingly naturalised, and are known only from a small number of populations. Twenty-four native taxa are recognised as extinct, whereas 8 naturalised taxa are considered to have either not persisted in Tasmania or have been eradicated. The sub-antarctic Macquarie Island, considered part of Tasmania, supports 49 species of vascular plants, of which 42 are considered native and 7 naturalised. For some basic statistics on the Tasmanian flora see Tables 1–3. Five new native taxa are recognised in the 2017 edition, three at the rank of subspecies and two at the rank of species (Appendix 1a). The names of several taxa have changed since the previous edition (Appendix 1b), including the recently described Pimelea leiophylla, a new endemic species recognised for the State. Several taxa have had their status changed since the previous edition (Appendix 1c). Twenty- one taxa were previously considered sparingly naturalised and are now considered to be fully naturalised. Cardamine tryssa was previously considered to be extinct in Tasmania, and has been recently re-discovered. Compared to the 2016 Census, this edition contains 79 fewer exotic taxa (Appendix 1d). These were listed in previous editions as sparingly naturalised, but a recent review by Baker et al. (in prep.) has found no conclusive evidence to demonstrate that they have, in fact, ever become naturalised. This review has led to numerous taxa having status changes in the 2017 edition and to the inclusion of a new status of doubtfully naturalised. Finally, the species, Leptecophylla juniperina, is no longer considered to occur in Tasmania. 3 Tasmanian Vascular Plant Census 2017 Acknowledgments This checklist was developed using BRAHMS (Botanical Research And Herbarium Management System) database management system. The authors would like to thank the BRAHMS team for making possible (and infinitely easier) the publication of an annual up-to-date census. In addition the authors would like to thank the APC (Australian Plant Census) group, whose work brings to our attention a myriad of taxonomic updates we might otherwise miss. We would like to thank Lynette Cave of the Tasmanian Herbarium for her assistance in checking the validity and publication details of numerous taxa. Mark Wapstra (ECOtas) and Wendy Potts (DPIPWE) provided useful comments on drafts of this publication and for these we are grateful.
