This key is designed for anyone who has an interest in finding out about the plants of south eastern New South Wales. It includes about 2,900 species of plants accompanied by about 10,000 images. It includes Eucalypts, but not ferns, orchids, grasses, or most sedges or rushes. There are about 3,900 relevant species in the area covered by this key.
The key mostly uses easily seen characters and a minimum of technical terms to help with the 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.
In most cases, the use of a hand lens or a low power microscope is not necessary for identification, except when counting the number of flowers/florets in a flower head, and deciding whether hairs on stems are stellate (multiple hairs arising from a point, looking like a star), branched, or simple. Identification needing the use of a high power microscope is beyond the scope of the key.
