Acknowledgments.

I have once again to acknowledge the help and encouragement given me by Mr. G. O. K. Sainsbury, whose unrivalled knowledge of the New Zealand Moss Flora has been ungrudgingly placed at my disposal. All mosses have been submitted to him for determination or confirmation, and to his assistance much of the value of the paper is due. Mrs. E. A. Hodgson has rendered similar service with the hepatics and has unsparingly determined all species collected.

I desire also to acknowledge with gratitude the valuable assistance rendered by Mr. Roy Traill, who either arranged or provided transport to the more distant places visited, and from whose company and intimate knowledge of the tracks and forest flora I profited not a little.
