Art. XXXIX.—List of Lichenes and Bryophytes collected in Stewart Island during the Botanical Survey of 1908. By L. Cockayne, Ph.D. [Read before the Philosophical Institute of Canterbury, 6th October, 1909.] The following were, with a few exceptions, collected in October, 1908, during my investigation of Stewart Island botany for the Department of Lands and Survey. The identifications were made by Dr. G. Lindau (Royal Botanical Museum of Berlin), Dr. V. F. Brotherus (Helsingfors), and Mr. F. Stephani (Leipzig), to which eminent specialists I am deeply grateful. Unfortunately, the identifications arrived too late for insertion in my report to the Department. For the sake of easy reference, the species are arranged in alphabetical order, and their position in Hooker's “Handbook of the New Zealand Flora” is also cited. Mr. J. W. Murdoch rendered most valuable assistance in collecting, and to him my warmest thanks are due. Stewart Island is extremely rich in bryophytes and lichens, and this list must be looked upon as merely a small contribution towards the knowledge of these interesting plants. Lichenes.
