branches, particularly on the upper forest margin, Ulota spp. are abundant. Dicranum trichopodum, which is far from rare at the lower levels, sometimes has setae up to four inches long. On Kelly's Hill Orthotrichum beckettii grows prolifically on Carmichaelia odorata in the subalpine scrub. I. Logs, Fallen Trees, and Decaying Timber. Wood in an advanced stage of decomposition is the ideal sub-stratum for Rhizogonium distichum, R. bifarium, R. novae-hollandiae, and Sematophyllum amoenum. Pterygophyllum quadrifarium and P. dentatum, neither of which appears to be common nor restricted to rotten wood, is very commonly found there in localities where it grows. I have failed to note either of them in the Bealey Valley. Timber in a less advanced stage of decay is usually occupied by mosses from the following list: Holomitrium perichaetiale, Dicranum trichopodum, Dicranoloma spp., Hypnum cupressiforme, Ptychomnion aciculare, Brachythecium rutabulum, Thuidium furfurosum, Acrocladium auriculatum, Acanthocladium extenuatum, Rhacopilum strumiferum, Sematophyllum amoenum, or Eurhynchium asperipes. The associated hepatics include Chandonanthus squarrosus, Chiloscyphus beckettianus, C. sinuosus, Schistochila tuloides, Lophocolea spinifera, L. sp., and Plagiochila spp., but here, as in some other stations, only the mosses were systematically collected or studied. J. Swamps and Bogs. Swamp mosses include first and foremost Sphagnum antarcticum, in which reddish patches of Bryum blandum may occasionally be observed (e.g., Kelly's Saddle, Mount Barron, Temple Basin). Where the water is moving slowly from the swamp, Drepanocladus brachiatus or D. fluitans may appear, and it is probable that Berggren secured Bryum huttonii from such an area of Swamp. Bryum curvicollum grows in swampy patches on the Bealey Flats, with Carex berggreni. Bogs, on the other hand, usually have as their commonest mosses Rhacomitrium lanuginosum var. pruinosum, dwarf Campylopus torquatus, C. clavatus, C. introflexus, or C. bicolor, and Rhacocarpus australis. Hepatics are few and lichens mostly species of Cladonia—C. pycnoclada, C. aggregata, C. retipora, and C. pleurota—and a dwarf white coralloid lichen Siphula medioxema particularly common on Avalanche Peak. It is noteworthy that the bog mosses and lichens are practically identical with those of exposed rock outcrops. Acknowledgments. The preparation of this paper has only been possible by reason of the assistance so ungrudgingly given by Mr. G. O. K. Sainsbury, Mrs. E. A. Hodgson, and Dr. H. H. Allan with the mosses, hepatics, and lichens respectively. Indeed, all the liverworts and lichens mentioned have been identified by the above authorities. As the paper is concerned with the mosses in particular, unknown and doubtful species have been referred to Mr. Sainsbury for identification or verification; and it is true to say that without his help and criticism this paper could scarcely have been attempted. All field notes and observations are my own, and for the accuracy of these I take full responsibility.
