One out of ten of New Zealand plants is under threat of extinction in the wild. As habitats have changed or disappeared, populations of some plants have dwindled to just a few individuals. This is a comprehensive guide to New Zealand's rare and endangered plants. Colour photographs and precise botanical descriptions identify over 95 species that are most at risk. For ease of reference in the field, entries are arranged by group, and cover trees and shrubs, climbers and scramblers, herbaceous plants (including orchids, grasses and sedges), ferns and fern-allies, parasites and semi-parasites. The authors suggest strategies for conservation and set forth a code of conduct for those who find these plants in the wild.
