Art. XXV.—Some Hitherto-unrecorded Plant-habitats (III). By L. Cockayne, Ph.D. [Read before the Philosophical Institute of Canterbury, 11th December, 1907.] With regard to some of the species noted below, it is possible they may be mentioned prior to the publication of this paper in one or other of the reports I am preparing for the Department of Lands and Survey, but nevertheless I am keeping them here, as it seems convenient to have such unrecorded species together in one publication. A considerable number of the species recorded are from Stewart Island, but certain critical plants from that island are omitted until I publish a general account of the vegetation of that district. of the remainder, the only one worthy of special mention is Pittosporum patulum, a plant hitherto only recorded from the north-west Nelson district, and which has not as yet been found in the intervening country, much of which is certainly well suited as a habitat. Mr. Bond, who collected the specimen, noted only two plants, which were growing within two chains of one another just inside the edge of the bush.
