An Illustrated Guide to Common Weeds of New Zealand. 3rd ed. 2010. col. photogr. XXXII, 416 p. gr8vo. Paper bd.

This guide to the identification of weeds in New Zealand is now in its third edition and covers over 600 species. The authors aimed to include all common weeds, including garden escapes, introduced plants, and some plants which may be useful pasture components but which can be a nuisance in the garden or in horticultural crops. Native species are listed when they are major weed problems of pastoral land in some regions, or when they may be mistaken for weeds which they resemble. Each plant receives a general introduction, and is then described in detail; the usefulness or toxicity of the plant is also addressed, and derivation of botanical names is given. Plants are listed by both botanical and common names, and indexes enable easy searching, but there is also a section which helps you to identify a plant from information about flower colour and size, the kind of plant it is and where it occurs. The text has been updated to accommodate changes to the legislation governing pest plants.
