The family Geocalycaceae are one of the largest families of leafy liverworts in India consisting of 9 genera and 27 species belongs to two subfamilies. Present study reports the distribution of members of this family in Kerala state. In Kerala the family Geocalycaceae are represented by 11 species belonging to three genera viz., Heteroscyphus (6 species), Chiloscyphus (3 species) and Lophocolea (2 species). Among these Chiloscyphus muricatus and Heteroscyphus bescherellei are new record of occurrence for the state of Kerala.

Reproduction in bryophytes is by asexual as well as sexual means. Asexual reproduction is a significant adaptation to special environments and occurs by a large variety of methods. During the last few decades, many of the bryophytes, particularly the dioecious ones are reported to have registered a decline in their fertile populations. There is, therefore, a need to understand the reasons for their disappearance.

Der Südrand des Kyffhäuser im nördlichen Thüringen ist eine der trockensten (500 mm Jahresniederschlag) und wärmsten (10° Jahresmitteltemperatur) Regionen Deutschlands. Zudem wird er von Zechstein-Gipsen gebildet, die sehr wasserdurchlässig sind und nur eine geringe Bodenauflage haben, sodass große Partien von Natur aus waldfrei sind. Daraus resultiert eine für Deutschland ziemlich einzigartige Vegetation, die nur in Anklängen auch im Südharz und im Unstruttal zu finden ist. Sie besteht aus kontinentalen Steppenelementen (Stipa, Adonis, Mannia fragrans), mediterranen Elementen (Riccia ciliifera, Tortula brevissima, Tortula revolvens, letztere von Reimers als Wüsten-Steppenmoose bezeichnet) und arktisch-alpinen Elementen (Athalamya hyalina, Tortella densa).

Growth of nine species of cyanobacteria was observed on eight species of bryophytes (thalloid liverworts and mosses) growing in the polyhouse, Bryophyte conservatory (Moss House), at National Botanical Research Institute, Lucknow, India. Bryophytes were cultured in the laboratory and transferred to polyhouse for hardening and acclimatization. Cyanobacterial growth was observed on the bryophytes as a contamination due to which there was suppression of bryophyte growth. It was evident that cyanobacteria played a significant role of allelopathy.

Combined data from chloroplast and mitochondrial genome sequences showed paraphyly of bryophytes
(2013)
The present study was conducted using chloroplast and mitochondrial genome sequences of plants to gain insight on evolutionary relationship of bryophytes. The representative taxa were selected considering the availability of both organelle genome sequences. Phylogenetic analysis using combined data from chloroplast and mitochondrial sequences infer paraphyly of bryophytes.

Les Vosges appartiennent, du point de vue bryologique, aux régions de l’Europe moyenne les plus riches et les plus intéressantes en espèces. Malheureusement, il manquait pour les présenter une flore synthétique. En 1989, l’auteur avait publié à son compte une première édition en 100 exemplaires d’une Bryoflore des Vosges dans laquelle, pour la première fois, toute la littérature bryologique avait été exploitée et enrichie par ses données personnelles. Celle-ci avait été complétée par un carroyage qui donnait ainsi un aperçu de la connaissance bryologique de cette région. Treize ans plus tard, une deuxième édition de ce travail fut publiée dans la revue « Limprichtia ». Les deux éditions furent traduites en français parce qu’il était important qu’une flore régionale portant sur une partie du territoire de la France soit publiée dans la langue de ce pays. Le texte de la première édition avait été traduit par une collaboratrice de l’auteur et fut revue par René Schumacker. Les compléments apportés au texte de la deuxième édition ont été traduits par Michael Häussler , René Schumacker en ayant à nouveau revu la traduction. Francis Bick a revu le texte et a traduit les nouvelles adjonctions apportées à la Bryoflore des Vosges à l’occasion de cette troisième édition.

The present study is a compilation of moss flora of Western Himalayas (India). This compilation listed 745 species of mosses, belonging to 19 orders; 55 families and 230 genera. Out of these 17 species have been reported endemic from Western Himalayas. 196 species have been synonymized and status of 86 species is still doubtful i.e. unresolved name. At present out of 745 only 463 species are validly known from this mountain range of India

Im Rahmen einer jetzt schon ganzen Reihe von Gebietsmonographien soll hier die Moosflora ausgewählter „hot spots“ im Lahntal zusammengestellt werden. Grund ist, dass – wie schon früher erwähnt – eine einfache Möglichkeit eröffnet werden soll, sich ohne große Recherchen über die Besonderheiten der deutschen Moosflora zu informieren, zumal aber auch der Personenkreis, der solche Zusammenstellungen erbingen kann, insbesondere aus eigener Anschauung, immer kleiner wird und bei der deutlichen Abnahme von floristisch ausgebildeten Bryologen oder lokalfloritsisch orientierten Mooskennern eine Zusammenstellung von Nöten wird.

Barail Wildlife Sanctuary (BWS) lies amidst the tropical forests of the state Assam, India between the coordinates 24o58' – 25o5' North latitudes and 92o46' – 92o52' East longitudes. It covers an area of about 326.24 sq. km. with the altitude ranging from 100 – 1850 m. An ongoing study on the group Marchantiophyta (liverworts, bryophyta) of BWS reveals the presence of 42 species belonging to 24 genera and 14 families. Among these, one genus (Conocephalum Hill) and 13 species are recorded as new for the state of Assam, eight species have been found which are endemic to India, seven species are recorded as rare and one species, Heteroscyphus pandei S.C. Srivast. & Abha Srivast. as threatened within the study area. Out of 24 genera identified, 46% have been found growing purely as terrestrials, 25% as purely epiphytes and 29% have been found to grow both as terrestrials as well as epiphytes. Among these, a diverse and interesting range of microhabitats have also been observed for each taxon. It has been found that genera having vast range of microhabitats comprise large percentage of the total liverwort flora of BWS.

The present phylogenetic analysis was conducted using mitochondrial genome sequences of plants to infer evolutionary relationship of bryophytes. Paraphyly of bryophytes was shown by reconstructed trees. Liverworts are the first to diverge therefore appeared as sister to land plants in nucleotide based trees. However protein sequences based tree show mosses and liverworts to form a joint clade. Hornworts formed sister relationship with vascular plants.

Fontinalis antipyretica var. mollis is recorded for Spain, which differs by orbicular, not keeled leaves. The presence in the same tufts together with var. antiypretica reveals that it is a somatic mutant of the latter. A form of Pellia epiphylla was observed which has wide thallus margins of unistratose cells resembling those of Aneura maxima. A Campylopus was collected resembling C. flexuosus but with ventral stereids in transverse section of the costa. It is described as C. flexuosus var. anomalus. An (unsuccessful) attempt has been made to find the locality in which P. Allorge found Campylopus setifolius for the only time in the Iberian Peninsula. The bryophilous fungus Octosporella jungermanniarum is reported as new to Spain. Dicranodontium didymodon, known before from the Himalaya and western China, is reported as new to Europe.

The availability of organelle genome sequences in public databases facilitates the reconstruction of land plants phylogeny. Therefore the present phylogenetic analysis was conducted using chloroplast genome sequences of plants to study phylogenetic relationship of bryophytes. The representative taxa were selected considering the availability of organelle genome sequences in database. Inferred tree topologies showed paraphyly of bryophytes with sister relationship between hornworts and vascular plants irrespective of the method (Maximum Likelihood and Bayesian Inference) and type of sequences (Nucleotide and Protein) used. Among bryophytes liverworts are the first to diverge therefore appeared as sister to land plants. Moreover land plants formed a monophyletic group.

Allelopathic effect of Stichococcus bacillaris Nageli (Green Alga) on the growth of two bryophytes
(2013)
Stichococcus bacillaris (Green Alga) growth was observed as a contaminant on two taxa of bryophytes, a thalloid liverwort Lunularia cruciata (L.) Dumort. ex. Lindb. and a hornwort Folioceros physocladus Bharad. ex Schiffn. et Pande, growing on soil in pots in acclimatization chamber of Moss House at National Botanical Research Institute, Lucknow, India. Due to this algal contamination, suppression of growth of these bryophytes has been observed. It was evident that succession of Stichococcus bacillaris and its interaction with bryophytes played a significant role of allelopathy.

In Europa wurden 30 Arten identifiziert, welche in Nordamerika in einem geschlossenen Bereich vorkommen, in Europa jedoch nur lokal vertreten sind. Wahrscheinlich wurden sie während dem Holozän verteilt. Diese Annahme wird durch die weitreichende Verstreuung in der nördlichen Hemisphäre unterstützt.
