This key is designed for anyone who has an interest in finding out about the plants of south eastern New South Wales. It includes 3209 species, accompanied by about 15,000 images.

The key uses a limited number of easily seen characters using a minimum of technical terms to help with identification of plants. It is not designed to key out to a single species, though sometimes it does. It is designed to narrow down the possibilities of what the plant might be to a limited number of species. The photos may then help you decide what your plant is.

Routine use of a hand lens or a macro app on your mobile phone will make identification easier, in particular for the feature Number of florets/tiny flowers in a flower head.

Plant Distributions
Plant distributions are derived from the maps generated for individual species in Spatial Portal, Atlas of Living Australia https://spatial.ala.org.au/ and from personal observation, and occasionally from the NSW Department of Environment and Heritage Bionet Atlas http://www.environment.nsw.gov.au/atlaspublicapp/UI_Modules/ATLAS_/AtlasSearch.aspx.

Records dated before 1 January 1983 have been disregarded. Distributions are given only for within the area covered by this key.

The eastern boundary of the Western Slopes runs south from north of Canowindra and along the Hume Highway to Albury.
