This is a facsimile reprint of Johnson and Brooke's classic work on the important and diverse wetland plant species of New Zealand. Designed as a field guide, it illustrates both native and naturalised plants of bogs, swamps, estuaries, and lakes, and covers the New Zealand botanical region, i.e., the three main Islands, the Kermadecs, the Three Kings, the Chathams, and the subantarctic islands including Macquarie. It covers ferns and their allies, conifers, stoneworts, and flowering plants. Mosses, liverworts, and lichens are not treated in this work. Superb line drawings complement the text which describes key features, distributions, and habitats. This reprint includes a new three-page section (plus references) of corrections and plant name changes since the original 1989 edition.
