Provides a means for identifying both native and naturalised vascular plants of the South West corner of Western Australia. Volume 1 focuses on ferns, grasses, sedges, lillies, orchids and other monocotyledons, while volume 2 presents trees, shrubs and broad-leafed plants, the dicotyledons. The format, with an illustrated key based on a combination of flower colour and shape, has been developed to be useful to people with little botanical knowledge.
