Scientific Plant Names Dictionary Version: 3.0 (14 November 2012)

This electronic dictionary file is generated from the information systems at the Western Australian Herbarium. It aims to provide an authoritative listing to aid with the correct spelling of these scientific names within common word processing software.

The dictionary files contain 12,641 entries representing botanical names, at various taxonomic ranks for the native and naturalised flora occurring in Western Australia. Specifically, the names are derived across kingdoms (5), divisions (26), classes and subclasses (46), orders (118), families and subfamilies (816) and genera (2715), the remainder belonging to the ranks of species, subspecies, varieties and formas.

This compares with 10,751 entries in 2009. This version contains vascular (angiosperm, gymnosperm, conifer, cycad, fern), non-vascular (moss, liverwort, hornwort), algae and fungi (including lichen) names now on the Census of Western Australian Plants. Note also that both current and synonymous names have been included.

This dictionary is summarised from 20,278 current and synonymous names, drawn from entries for 16,341 dicotyledons, 3,758 monocotyledons, 141 pteridophytes, 38 conifers and cycads, 201 bryophytes, 1117 alga, 827 lichens and 173 fungi. It also includes 1,224 alien plant names.
