Abstract The altitudinal distribution of bryophytes and lichens on Secretary Island is discussed, and comparisons are made with the region traversed by the Manapouri -Deep Cove track. The poverty of both species and individuals of lichens on Secretary Island and, to an even more marked degree, at Deep Cove, is probably caused by high rainfall favouring bryophytes. It is suggested that the near absence of Sphagnum, Marchantia, and related thallose hepatics from Secretary Island, and the comparative rarity of the mosses Weymouibia rnollis (epiphytic) and Thuidium (terrestrial) indicates either that the island receives lower rainfall or that lower light intensities prevail on the forest floor than in the Manapouri - Deep Cove area. Accompanying lists give 118 species of bryophytes and 140 species and varieties of lichens, all records being supported by herbarium specimens. The lichen list includes two genera (Lemmopsis and Aspiciliopsis) not hitherto recorded from New Zealand, and several new species.
