(c) Field Study.

Much of New Zealand remains bryologically unexplored, more particularly in South Island and in Stewart Island. In particular, this applies to the Southern Alps and to the country flanking them on the west, the mountainous country of Marlborough and Nelson, the Marlborough Sounds, and the mountainous country of Western Otago. Most of the writer's field study has been carried out in the Wairarapa, the Arthur Pass National Park, and in Otago; but collections have been made from Hokianga in the north to Stewart Island in the south. As a result, many mosses formerly considered rare have been found to be common in previously unexplored areas, new mosses have come to light, new stations have been discovered for uncommon species, and intermediate stations have been located for mosses previously noted only in widely separated localities.
