As part of the revision of Philonotis in South America, a sample collected in Chile perfectly matched the type specimen of P. brevifolia Herzog. This species described from Chile was considered conspecific with P. krausei (Müll. Hal.) Broth. by Seki, but is resurrected here on the basis of the shape, apex, margin of the leaves, the shape of the laminal cells and the position of the papillae on these cells. A lectotype is designated for P. brevifolia, and a detailed and illustrated description is provided, including the traits of new discovered male plants, amending the original description.
A new species of the family Trichocoleaceae, Leiomitra patriciana T. Katag., is described based on herbarium material collected from Papua New Guinea. The species is characterized by the following features: (1) the regularly to rather irregularly 1-pinnate ramification pattern; (2) sublongitudinal leaf insertion; (3) well-differentiated (anisophyllous) leaves and underleaves; (4) superficial cilia on the leaf disc; and (5) paraphyllia on the stem. A key to the species of Leiomitra is also provided.
A taxonomic history of Lepidozia cupressina (Sw.) Lindenb. (Jungermannia cupressina Sw.) is presented and its diagnostic characters and variability in sub-Saharan Africa are thoroughly discussed. Three subspecies are currently distinguished in this region, namely subsp. cupressina, subsp. africana (Steph.) Pócs, stat. et comb. nov., which occurs in the East African Indian Ocean islands and in the Eastern Arc of continental East Africa, as well as on the island of St. Helena in the Atlantic Ocean, and subsp. natalensis (Steph.) Pócs which is restricted to southern Africa. The other two subspecies, subsp. pinnata (Hook.) Pócs and subsp. quinquefida (Steph.) Pócs, are merged with the type subspecies of L. cupressina. A key to the recognition of the subspecies of L. cupressina is provided. Lepidozia chordulifera Taylor, a temperate species widely distributed in southern South America, is taxonomically assessed and some of its diagnostic traits are illustrated. It is considered to be conspecific with L. cupressina subsp. cupressina. Thanks to this taxonomic conclusion the range extension of L. cupressina in southern South America, including the Falkland Islands, is sanctioned and, additionally, distribution of this species is extended to subantarctic South Georgia and the northern maritime Antarctic. The current geographical range of L. cupressina is reviewed and mapped and it may be designated as a bipolar temperate species with numerous transitional stations in the tropical mountains. In the Southern Hemisphere L. cupressina is a typical Afro-American oreophyte.
A new species of Cololejeunea (Spruce) Schiffn., C. andamanensis sp. nov. is described from South Andaman Island. Cololejeunea pseudoschmidtii Tixier, previously known only from China, Malaysia, Philippines and Vietnam, is reported from South Andaman Island and the Great Nicobar Biosphere Reserve in the Nicobar group of the Islands of India.
Leptolejeunea latilobula Lei Shu, R.L.Zhu & Pócs, a new species from Fiji, is described and illustrated. This species stands out within Leptolejeunea on account of its large size of leaf lobule with four cells wide on the apical portion, lobe apex acute to apiculate, margin more or less dentate, and underleaf lobes linear, usually two cells long. Leptolejeunea serrulata Herzog is proposed as a synonym of Leptolejeunea tripuncta (Mitt.) Steph., previously known only from Fiji. A neotype of Leptolejeunea tripuncta is designated.
Three East and South-east Asian species of the genus Radula Dumort., viz. R. chinensis Steph., R. kojana Steph. and R. sumatrana Steph. are newly reported for the Indian bryoflora, from Arunachal Pradesh in Eastern Himalaya. Asexual reproduction through caducous leaves is described for the first time in R. sumatrana. Descriptions and illustrations of the three species based on Indian material are presented. A key to the Indian species of Radula is provided.
Bryophytes are important components of pine forests; however, the bryophyte layer is characterised by the dominance of a small number of taxa. Clear-cut logging changes microclimate conditions, while ploughing before planting young trees disrupts bryophyte patches. This promotes early successional species and can work in favour of species diversity provided that there are simultaneous regeneration of late successional species bryophytes. In the Tuchola Forest (north-western Poland), we investigated the occurrence and abundance of ground bryophytes using a chronosequence method. The study was carried out on plots that represented the following stand age classes: ≤ 10, 11–20, 21–40, 41–60, 61–80, > 80 years. Bryophyte richness was higher in the youngest stands than in the oldest ones. There are distinctive changes of species composition in the course of succession that range from colonists and stress-tolerant perennials to competitive perennials and from species growing in tufts to species growing in wefts. There are not “true” forest species even in the oldest stands. There is only a tendency for the exchange of species that prefer open habitats to species that prefer both forests and open habitats. However, clear cutting contributes to the increase of species richness of ground bryophytes and spatial diversity of plant patches in managed forests. The positive aspects of clear cutting can only be considered in relation to the species diversity in the oldest and managed stands but not with those in natural forests.
This paper is the first attempt to understand the genus Bazzania Gray (Marchantiophyta: Lepidoziaceae) in Peninsular Malaysia. Eleven new records for Peninsular Malaysia are reported. They are Bazzania albifolia Horik., B. angustitipula N.Kitag., B. asymmetrica (Steph.) N. Kitag., B. bicrenata N.Kitag., B. bidentula (Steph.) Steph. exYasuda, B. erosa (Reinw., Blume & Nees) Trevis., B. friabilis N. Kitag. & T. Kodama, B. horridula Schiffner, B. pseudovittata N.Kitag. & T.Kodama, B. serpentina (Nees) Trevis. and B. uncigera (Reinw., Blume & Nees) Trevis. The first five species are new to the country, Malaysia. An identification key for all the Bazzania species reported for Peninsular Malaysia is provided.
Twenty nine South European specimens of Sphagnum centrale, S. palustre, S. papillosum and S. magellanicum were studied with 15 microsatellite markers. In contrast with eastern North American populations, our analysis showed a genetic overlapping between S. centrale and S. palustre in mixed populations. Moreover, Mediterranean species showed a genetic richness (total number of alleles) higher than that calculated in conspecific American samples. As Mediterranean Sphagnum bogs are remnant populations, microsatellites could well work for selecting source populations in order to recover Mediterranean peatlands.
