Abstract201.Calycularia crispulaMitt. new to Mexico and the whole America. It is the first record outside Asia. 202. A type study ofFimbriaria nanaLindenb. revealed that it is synonymous withAthalamia hyalina(Sommerf.) Hatt. 203. Fossombroniaceae Hazsl. 1885 has to replace Codoniaceae Klinggr.1858 nom. illeg., becauseCodoniaDum. 1822 is illegitimate. 204.Herzogobryumaterrimum(Steph.) c. n. (≡Cephalozia aterrimaSteph.) has to replaceH. filariumGrolle 1975. 205.KorrnickiaSteph. 1917 is regarded as a synonym ofSymphyogynaNees et Mont. 1836 andK. cylindricaSteph. 1917 is placed in synonymy ofS. mexicanaSteph. 1909.206. The detection of the perianth ofLophocolea spectabilisSteph. (≡Heteroscyphus arnelliiFulf.) necessitates a transfer asLeptoscyphus spectabilis(Steph.) c. n. 207. All records ofPreissiaCorda from Latin America are rejected.P. barbataHerz. 1921 is referred to as syn. nov. ofMarchantia chenopodaL. 1753. 208.Riccia crustataTrab. was validly published in 1916 already, but has been generally overlooked hitherto. 209.Symphyogyna brasiliensis. Nees et Mont. is widespread in the Neotropics and Africa. Several African names are treated as synonyms. 210. The monotypic genusWiesnerellaSchiffn. is newly recorded from New Guinea and the Mascarenes. The Mascarene record is the first one outside Asia.

摘要:

AbstractInflorescences ofDicranum scopariumcontain 7–9 archegonia on average compared with 13–15 inD. majus. InD. majuspolysety was observed in 55% of fertile shoots. There is no evidence that the occurrence of polysety inD. majusis associated with any increase in the number of archegonia. This was interpreted to show that all inflorescences contained four or five ripe archegonia at the time of fertilization. Since monosetous inflorescences were more common than polysetous ones, it was concluded that the supply of antherozoids was not saturating for fertilization. InD. scopariumpolysety was observed in only 5% of fertile shoots.

摘要:

AbstractThe chromosome numbers in the genusGymnostomiella, G. vernicosa n=13, and in the three members of Bartramiaceae,Anacolia sinensis n=6,Philonotis angustata n=12 andP. revoluta n=6 are reported for the first time. The counts forPhyscomitrium cyathicarpum n=52,P. repandum n=52,Bartramia hallerana n=9,B. subpellucida n=6 andPhilonotis falcata n=12 are at variance with earlier reports. Intraspecific polyploidy is recorded inPhilonotis turneranawithn=6 12. Quadrivalents are observed inPhilonotis angustata. A dimorphic bivalent, rare in monoecious bryophytes, is observed inBartramia hallerana. Unlike that of many moss species, the smallest member of the set is heteromorphic inBartramidula bartramioides,Philonotis calcarea,P. revolutaandP. turnerana.

摘要:

AbstractData from hemispherical (‘fisheye’) photographs are presented from twenty bryophyte sites, including open grassland and rock outcrops of various slopes and aspects, habitats of mountain species on shaded cliffs and in corries, and wooded habitats of lowland atlantic species. These demonstrate effects of slope and aspect on both instantaneous and total energy income in direct sunshine, especially marked during the winter half of the year. Corrie habitats of northern atlantic species such asHerberta aduncaandMastigophora woodsiiwere exposed to direct sun only for a limited period in summer, with peak direct irradiance in June (about half that for an unobstructed level site in the examples considered). Wooded habitats of lowland atlantic species received their peak irradiance (both direct and diffuse) immediately before leaf expansion in spring; direct irradiance at this period relative to an unobstructed level site ranged from 0.8 (instantaneous)/0.35 (daily total) (Plagiochila spinulosa, Scapania gracilis: Devon) down to negligible values (Drepanolejeunea hamatifolia, Aphanolejeunea microscopica; ravine sites in N. Wales and Yorkshire).
