AbstractThe discovery ofSphagnum subfulvumin Western Ireland is reported and the Irish specimens are described. The habitat of the species at Errisbeg, Co. Galway, is described and compared with the occurrences in Norway. It is concluded that the ecology ofS. subfulvumat Errisbeg closely resembles its ecology in Norway where it is an intermediate/rich fen species, and in the‘mud-bottomto hummock’vegetational gradient it belongs to lawn and low hummock vegetation. The occurrence ofSphagnum subfulvumon flushed mountain slopesin West Mayo is apparently related to localised basic conditions as indicated by its association withSchoenus nigricans, Anagallis tenella, Selaginella selaginoidesandBreutelia chrysocoma. Sphagnum subfulvumis reported from raised bog in Co. Roscommon. Its occurrence in ombrotrophic vegetation is somewhat unexpected but the ombrotrophic vegetation in Western Ireland includes some species which are restricted to minerotrophic vegetation elsewhere.

摘要:

AbstractBased on a comparative morphological study (including type material)Neckera laeviusculaGeh. in Herz.,Neckera besseri(Lob.) Jur. andHomalia webbianaMont., which have been treated as conspecific, are shown to be distinct species. The differences betweenHomaliaandNeckeraare discussed andNeckera besseriis placed in the genusHomaliaas originally described.

摘要:

AbstractThe distinction between mamillae and papillae is arbitrary in two of the genera studied, the latter originating as the former inGymnostomum aeruginosumandAnoectangium warburgii. G. aeruginosumandG. calcareumare treated as separate species, both of which can be distinguished fromA. obtusifolium. Moreover, attention is drawn to the fact thatA. obtusifoliumlacks the differentially thickened leaf cells ofMolendoa sendtnerianaand ofM. sendtnerianavar.tenuinervis.

AbstractMesochaete grandiretisDix. is reduced to synonymy withM. taxiforme(Hampe) Watts&Whitel. and a comparison is made withM. undulataLindb. which has much smaller cells and also differs in perigonial and perichaetial leaves and capsule shape.

摘要:

AbstractFissidens traversii, a new species from Queenslahd, Australia, is characterised by the rounded leaf apex, costa papillose and finishing short of the apex, mamillose, multipapillose cells, short dorsal lamina and vaginant laminae (which usually have a marginal strip of transversely elongated calls in the lower half), reaching almost to the apex of the leaf.

AbstractBased on recent extensive collections of J. K. Bartlett between Latitude 34°30′S and Latitude 47°S, a survey of theCampylopusflora of New Zealand is presented.C. paludosusJ. K. Bartlett et J.-P. Frahm andC. pyriformis(Schultz) Brid. var.hamatusJ. K. Bartlett et J.-P. Frahm are described as new,C. flavoviridisDus. is reported new to New Zealand. TheCampylopusflora of New Zealand comprises nine species. A key is given for all species, plus additional ecological remarks.Chorisodontium aciphyllumis recorded as new to the New Zealand flora and comments are made on the systematic position of the taxonChorisodontium burrowsiiAllis.

摘要:

AbstractThe new combinationTetralophozia filiformis(Steph.) E. Urmi is proposed forChandonanthus filiformisSteph. So far this species has been known only from Asia and N. America. Recent collections show it to occur also in Europe, in the Cantabrian Mts., Spain. Here it grows in sheltered places on siliceous rocks in oceanic conditions. FromTetralophozia setiformis(Ehrh.) Schljak. (=Chandonanthus setiformis) it is distinguished by its smaller size, the leaf lobes are always more than twice as long as wide and their margins are not inflexed towards the stem.
