This set includes all 4 volumes currently in print ie volumes 2-5 inclusive as well as a second hand copy of the 1982 edition(The last one produced) of volume 1 which is now out of print. This is a very good copy.
Volume 1 describes all the indigenous vascular plants except the monocotyledons – the ferns and their allies, the conifers, and the dicotyledonous flowering plants. Special attention has been paid to keys to families, genera, and species. Line drawings by Nancy M. Adams assist identification in some difficult groups.
There are notes on hybrids and doubtful species, with mention of most names based on New Zealand types, and synonymies and bibliographic references are given. A section on the annals of taxonomic research covers the more important publications from Banks and Solander up to the end of 1958. There is an annotated list of names of authors, a catalogue of Maori names of plants, and a brief introductory essay on the New Zealand botanical region.
