Iwats.]、无边匐灯藓[Plagiomnium elimbatum (M. Fleisch.) T. Kop.]、异叶小羽藓[Haplocladium larminatii (Broth. et Par.) Broth.]和东亚小羽藓[Haplocladium strictulum (Card.) Reim.]。     

Distribution maps of Bryophytes in Britain and Ireland

Abstract

Eight epithets of Rigodium (R. araucarieti C. Müll., R. argentinicum C. Müll., R. brachypodium (C. Müll.) Par., R. nano-fasciculatum C. Müll. ex Thér., R. pendulum Herz. &; Thér., R. pseudo-thuidium Dus., R. solutum (Tayl.) Par., and R. tamarix C. Müll), lectotypified here, are listed with their nomenclature and pertinent details involving the careful identification of type specimens and original material. For Rigodium solutum (Tayl.) Par., a specimen from Taylor's original herbarium may likely be the holotype but had not been indicated as such by Taylor, the original author. A conservative approach for this situation is taken here by designating this specimen as a lectotype.     

Vittia salina L.Hedenäs & J.Muñoz,sp. nov., a new moss from Argentina

Abstract

A survey of the species of Campylopus Brid. reported from Sri Lanka (Ceylon) is presented. Of the 34 species that have been reported from this Island 16 are accepted at present. Campylopus nilghiriensis (Mitt.) Jaeg. is identical partly with C. goughii (Mitt.) Jaeg., partly with C. zollingerianus (C. Müll.) Bosch &; Lac., C. pseudogracilis Card. &; Dix. with C. goughii (Mitt.) Jaeg., C. caudatus (C. Müll.) Mont., C. reduncus (Reinw. &; Hornsch.) Bosch &; Lac. and C. trachythecius (C. Müll.) Jaeg. with C. comosus (Reinw. &; Hornsch.) Bosch &; Lac., C. herzogii Broth., C. subtricolor Lor. and probably also C. nodijlorus (C. Müll.) Jaeg. with C. aureus Bosch &; Lac., C nietneri (C. Müll.) Jaeg. with C. involutusz (C. Müll.) Jaeg., C. subgracilis Ren. &; Card. ex Gangulee and C. latinervis (Mitt.) Jaeg. with C. gracilis (Mitt.) Jaeg., and C. laetus (Mitt.) Jaeg. with C. savannarum (C. Müll.) Mitt. C. pterotoneuron (C. Müll.) Jaeg. is reduced to a variety of C. umbellatus (Arn.) Par. The occurrence of C. exasperatus Brid. on Sri Lanka could not be confirmed. Campylopus flagelliferus (C. Müll.) Jaeg. is reported as new to Sri Lanka.     

Observations on Hookeriales,I. The taxonomic status of African species of Sauloma (Hook. f. & Wils.) Mitt. (Hookeriales)

African members of the moss genus Sauloma (Hook. f. & Wils.) Mitt are evaluated. Sauloma tisserantii P. Varde from Oubangui, Sauloma humblotii (Ren. & Card.) Card. (= Lepidopilum humblotii Ren. & Card.) from the Comoros and S. africana Dix. & Thér. from Central Africa are all conspecific with Leucomium strumosum (Hornsch.) Mitt. (Hookeriales, Leucomiaceae), the first two names being synonymized with the latter for the first time. S. julacea C. Müll. in Par. nom. nud. correctly belongs within Meiothecium (Sematophyllaceae) and S. chloroclada C. Müll. in Broth. nom. nud. is Meiothecium chlorocladum (Broth.) Broth. Accordingly, the genus Sauloma has to be excluded from the bryoflora of mainland Africa and adjacent islands.

Taxonomic notes on New Zealand species of Tortula

Abstract

T. bealeyensis R. Br. ter, is reduced to synonymy with T. anderssonii Ångstr. and T. paehyneura Dix. to synonymy with Barbula ealobolax C. Müll.B. calobolax and B. calobolax var. angustinervia C. Müll. are transferred to the genus Willia. T. petriei Broth. is reduced to a subspecies of T. arenae (Besch.) Broth. Differences between this taxon and the ssp. arenae are outlined and T. arenae ssp. arenae is reported for the first time from the Auckland Islands. A lectotype is chosen for T. rubra Mitt, and T. subantaretiea Sainsb. is reduced to a variety of T. rubra. New Zealand plants referred to T. serrulata Hook. et Grev. are more correctly assigned to T. serrata Dix., which is endemic to New Zealand.     

New synonymy and typification in African Schlotheimia (Bryopsida: Orthotrichaceae)

Abstract

Schlotheimia grevilleana Mitt., Schlotheimia rigescens Broth., Schlotheimia laetevirens Broth., Schlotheimia bequaertii Thér. & Naveau and Schlotheimia brachypodia Thér. & Naveau are placed in synonymy with Schlotheimia ferruginea (Bruch ex Hook. & Grev.) Brid. The typification of Schlotheimia percuspidata Müll.Hal. is discussed and a neotype is proposed.     

Ditrichum austrogeorgicum: a synonym of D. hyalinum (Musci,Ditrichaceae)

Ditrichum austrogeorgicum (Card.) Seppelt, a species originally described in 1906 from South Georgia as Pseudodistichium austrogeorgicum Card., is considered to be conspecific with Ditrichum hyalinum (Mitt.) O. Kuntze. The latter had been first described in 1859 as Leptotrichum hyalinum Mitt. from material collected on the Falkland Islands and Hermite Island near Cape Horn, but it had been first recognized as a separate taxon, Didymodon longifolius (Brid.) Hook. f. & Wils. var. tenuifolius Hook. f. & Wils., in 1847. Pseudodistichium austrogeorgicum f. brevifolium Card. and P. austrogeorgicum var. longifolium Broth. in Card. & Broth. are reduced to synonymy with Ditrichum hyalinum. Some details of the type material of the last are illustrated.     

A revision of Chinese Thuidiaceae (s. l., Musci)

The study on Chinese Thuidiaceae was started in 19th century. However the present paper deals with the first revision of the family in China. There are 17 genera and 71 species in total including one subspecies. In this paper, several nomenclatural problems are treated, mainly involving 7 genera: Leptocladium Broth., Anomodon Hook. et Tayl., Haplocladium ( C. Muell. ) C. Muell., Claopodium (Lesq. et Jam. ) Ren. et Card., Bryonoguchia Iwatsuki et Inoue, Helodium (Sull.)Warnst. and Actinothuidium (Besch.)Broth. One new species, 3 new synonyms, includingone generic synonym and two specific synonyms, and one Chinese new name are reported.     

The moss genus Leptobryum and the identity of Pohlia integra

Abstract

Leptobryum Wilson (Bryaceae) consists of two species, viz., Leptobryum pyriforme (Hedw.) Wilson and L. wilsonii (Mitt.) Broth. Pohlia integra (Cardot) A.J.Shaw and three other species of Leptobryum, viz., L. escomelii Thér., L. pottiaceum Dusén, L. stellatum (Herzog) Broth. are reduced to synonomy under L. wilsonii. L. sericeum Kindb. is considered a doubtful species because no specimen could be located.     

A reassessment of some Asian species of Heterophyllium (Schimp.) Kindb. (Pylaisiadelphaceae,Bryophyta)

Introduction. Heterophyllium albicans Thér., H. henryi Tixier, H. micro-alare (Broth. & Paris) Broth. and H. tonkinense (Broth. & Paris) Broth. were all either poorly known species or known only from the type collections since their inception.

Methods. Examination of the type material confirmed that the alar cell structure in these species do not conform to the generic concept of Heterophyllium (Schimp.) Kindb. The study also revealed some new features previously unreported in these species, i.e., the filamentous pseudoparaphyllia, one of the characteristic features of the genus Isopterygium Mitt.

Key Results & Conclusions. Three new combinations, Isopterygium albicans (Thér.) Y.Jia & S.He, I. micro-alare (Broth. & Paris) Y.Jia & S.He, and I. tonkinense (Broth. & Paris) Y.Jia & S.He are proposed. Heterophyllium henryi Tixier is treated as a new synonym of Brotherella henonii (Duby) M.Fleisch.     

Phylogenetic relationships between Bryum and supposedly closely related genera

Abstract

The phylogeny of the genus Bryum was studied using cladistic analyses under the maximum parsimony criterion of evolution of anatomical and morphological characters. Three analyses were made with 32 Bryum species plus 20 species from genera supposedly closely related to Bryum, and with Amblyodon dealbatus (Sw. ex Hedw.) Bruch & Schimp., Meesia uliginosa Hedw., and Leptostomum macrocarpum (Hedw.) Bach. Pyl., as outgroups. It is here suggested that under earlier systematic concepts the genus Bryum is paraphyletic. A clade with Bryum billarderi Schwägr., B. capillare Hedw., B. donianum Grev., B. russulum Broth. & Geh., Rhodobryum giganteum (Schwägr.) Paris, and R. keniae (Müll. Hal.) Broth. are circumscribed by spathulate stem leaves that are crowded in the stem apex, suggesting that the rosulate species of Bryum are more closely related to Rhodobryum than to the rest of Bryum. Stem leaf costae without stereids and spores that mature in the winter are synapomorphies for a clade with Anomobryum julaceum (P. Gaertn. et al.) Schimp. and Bryum argenteum (Hedw.). The tropical species B. cellulare Hook. and B. flaccum Wilson ex Mitt. appear in a clade with Plagiobryum zieri (Dicks. ex Hedw.) Lindb. and Synthetodontium pringlei Cardot. In one analysis, B. limbatum Müll. Hal., Epipterygium tozeri (Grev.) Lindb., Leptobryum pyriforme (Hedw.) Wilson, and Roellia roellii (Broth. ex Röll) H.A. Crum came out in a clade with Mniobryum atropurpureum (Wahlenb.) I. Hagen, Mnium hornum Hedw., Pohlia cruda (Hedw.) Lindb., P. longicollis (Hedw.) Lindb., and Pseudopohlia didymodontia (Mitt.) A.L.Andrews. It is here suggested that gametophytic features, such as the orientation and anatomy of the stem leaves and the appearance of vegetative propagules, are important for the internal relationships within the studied ingroup, whereas characters related to the sporophyte, especially those of the peristome, may obscure phylogenetic relationships. Most of the subgenera and the sections of Bryum, as defined by earlier authors, appear to be paraphyletic. However, due to the low stability of most clades it is suggested that analyses including anatomical, morphological, and molecular data are needed.

A revision of the moss genus Sciaromium (Mitt.) Mitt. I. General remarks and the section Aloma Dusén

Abstract

The generic name Sciaromium (Mitt.) Mitt. that was originally used as a sectional epithet in Leskea is synonymous with Echinodium Jul E. madeirense Jur. [= E. spinosum (Mitt.) Jur.] is selected as the lectotype of the genus Echinodium. A historical review of taxonomic and nomenclatural problems in Sciaromium is provided and taxa that had previously been excluded from this genus are briefly discussed. Sciaromium flavidulum Dusén is a Eurhynchium and the combination E. flavidulum (Dusén) Ochyra is made. Sciaromium sect. Aloma Dusén is synonymous with Eurhynchium since E. flavidulum serves as the type species of this section. The taxonomic position of S. gracile Dusén is discussed and this species is considered synonymous with Amblystegium chilense Lor., which is transferred to Pseudoleskea and the appropriate new combination P. chilensis (Lor.) Ochyra made. Type specimens of S. bellii Broth., S. elimbatum Broth. & Watts and S. forsythii Broth. in Broth. & Watts are briefly described and illustrated; these species are reduced to synonymy with the polymorphic Cratoneuropsis relaxa (Hook. f. & Wils.) Fleisch. in Broth.     

Revision der Gattung Thysanomitrium Schwaegr. (Dicranaceae) in Südamerika.

Abstract

The differences between Thysanomitrium Schwaegr. and Campylopus Brid. are discussed and regarded as insignificant. Therefore the six Thysanomitrium species reported from South America in the Index Muscorum are critically revised. T. yunqueanum C. Müll. and T. miserum Broth. are synonyms of Campylopus richardii Brid., and T. schiffneri Broth. and T. arenaceum Broth. are placed in the genus Campylopus as new combinations. Also T. arenaceum is reported from a new locality in Brazil. No material could be found in herbaria of T. wainoi Broth. and T. gastrotis C. Müll.     

A contribution to the knowledge of epiphyllous bryophytes of Bioko Island (Equatorial Guinea), including additional remarks on non-epiphyllous species

Abstract

A collection of epiphyllous bryophytes from Bioko Island was investigated. It contained 57 epiphyllous bryophytes, comprising 55 hepatics and two mosses. Three taxa, Cololejeunea eustacei Pócs, Colura calderae Pócs and Lejeunea halei Robinson subsp. africana Pócs, are new to science. Cololejeunea papilliloba Steph. is new to Africa, five species of hepatics are new to West Africa, and an additional 31 species of hepatics are newly reported from Bioko Island. The second part of the paper deals with records of non-epiphyllous collections. Fourteen species are reported for the first time for Bioko Island. Actinodontium dusenii Broth. is made a synonym of Actinodontium streptopogoneum Broth. The following new combination is proposed: Wijkia rigidicaule (Müll.Hal. ex Broth.) Frank Müll., comb. nov. (Basionym: Acanthocladium rigidicaule Müll.Hal. ex Broth.).     

Obituaries

Abstract

The history and nomenclatural problems of the name Limbella are reviewed, the correct citation of the generic name being Limbella (C. Muell.) Broth. The genus consists of two species, L. tricostata (Sull.) Broth. and L. fryei (R. S. Williams) Ochyra which are described. L. tricostata is endemic to the Hawaiian Islands and L. fryei to Oregon on the Pacific coast of North America. Sporophytes are recorded for the first time in L. tricostata. The family relationships of Limbella are discussed and it is placed in the Thamnobryaceae, close to Thamnobryum.     

New records and a bibliography of the mosses of Pakistan

Abstract

Forty mosses are recorded for Pakistan, of which six appear to be new records for that country. Timmiella subintegra Dix. is reduced to synonymy under T. barbuloides (Brid.) Moenk., and there are notes on the typification of Pilotrichum pluvinii Brid. (Cryptoleptodon pluvinii (Brid.) Broth.).     

Notes on the genus Thamnobryum in Macaronesia (excluding the Cape Verde Islands)

Abstract
