Summary.

This paper is an attempt to show the distribution of the moss flora of New Zealand by classifying approximately 3,500 locality records under the Botanical Districts, as defined by L. Cockayne for the phanerogamic flora. It will enable future investigators to decide what localities represent an extension of the known distribution, while serving to show the known range of individual mosses. A study of Table V shows that the number of species known from any Botanical District is almost directly proportional to the attention that area has received from bryologists, unexplored area such as the Sounds-Nelson District having a meagre list at present of 84, against 331 for Canterbury or 242 for Auckland. Inferentially, a large accretion of species to the florulae of most districts is to be expected. Finally, the appended list of mosses will serve as a check-list of the New Zealand moss flora.
