Updates to Western Australia's vascular plant census for 2018.

Abstract

The census database at the Western Australian Herbarium (PERTH), which provides the nomenclature for the website FloraBase (Western Australian Herbarium 1998-), lists current names and recent synonymy for Western Australia's native and naturalised vascular plants, as well as algae, bryophytes, lichens, slime moulds and some fungi. The names represented in the census are either sourced from published research or denote as yet unpublished names based on herbarium voucher specimens. This paper summarises the changes made to vascular plant names in this database during 2018. One hundred and twenty-nine taxa were newly recorded for the State, of which 24 are naturalised and 41 have been added to the Threatened and Priority Flora list for Western Australia (Western Australian Herbarium 1998-). A total of 185 name changes were made, including the formal publication of 29 phrase-named taxa. Plant groups for which a number of name changes were made include Hydrocotyle, Drosera, Lepilaena and Zygophyllum (transferred to Roepera). Numerous phrased-named taxa in the genus Baeckea were formally published under an expanded circumscription of Hysterobaeckea. Cases where there has been a change of taxonomic concept, misapplication, exclusion or rank change are also included.
