to do this thesis in the actual form without the support and interaction of several persons. Most of all I want to thank the persons supervising me through the whole process with the evolution of the Neckeraceae: Johannes Enroth, Sanna Huttunen, Lars Hedenäs, and Dietmar Quandt. I have enjoyed a lot taking part in this intensive collaboration. The knowledge of the senior scientists was invaluable in offering the essential background information, in learning the relevant methods and helping to solve problematic questions. The international nature of the collaboration made it possible to compare ways to do and share information between different laboratories and countries. In addition, due to the closely related research subject of Volker Buchbender, we had excellent opportunities for interesting discussions comparing our results and to produce joint data for both of the projects. I am also grateful to the other cooperation partners from past or ongoing projects: Michael Grundmann, Kai Müller, Jesus Muños, Martin Nebel, Markus Preußing, Fred Rumsey,

O’Shea 141 Fawnbrake Avenue, London SE24 0BG, U.K. Abstract. The nine species and two varieties of Schoenobryum reported for Africa were investigated, and no characters were found that uniquely identified any of the taxa to be other than the pantropical Schoenobryum concavifolium. The following nine names become new synonyms of S. concavifolium: Cryphaea madagassa, C. subintegra, Acrocryphaea robusta, A. latifolia, A. subrobusta, A. tisserantii, A. latifolia var. microspora, A. plicatula and A. subintegra var. idanreense; a lectotype is selected for Acrocryphaea latifolia var. microspora P.de la Varde.

A total of 63 taxa belonging to Bryophyta (22 families 37 genera 44 species), Marchantiophyta (7 families 11 genera 18 species), and Antho- cerotophyta (1 family 1 genus 1 species) were determined, and the liverwort index was 30.2%. The predominant life form was the mat form. The rates of bryophytes dominating in mesic to hygric sites were higher than the bryophytes mainly observed in xeric habitats. These values indicate that such forests are widespread in this study area. Moreover, the rock was the substrate type, which plays a major role in providing micro-habitats for bryophytes. We suggest that more detailed studies of the bryophyte flora should be conducted on a regional scale to provide basic data for selecting indicator species of Gotjawal and evergreen broad-leaved forests on Jejudo Island. Keywords: bryophyte, Aewol Gotjawal, liverwort index, life-form Jejudo Island was formed by volcanic activities and has geological, ecological, and cultural aspects (Jeong et al., 2013; unique topological and geological features.

The incomplete preservation and lack of key characters that could define the position of an ancient moss in modern classification remain the problem. Carboniferous records are still impossible to refer to any of the modern moss taxa. Numerous Permian protosphagnalean mosses possess traits that are absent in any extant group and they are therefore treated here as an extinct lineage, whose descendants, if any remain, cannot be recognized among contemporary taxa. Non-protosphagnalean Permian mosses were also fairly diverse, representing morphotypes comparable with Dicranidae and acrocarpous Bryidae, although unequivocal representatives of these subclasses are known only since Cretaceous and Jurassic. Even though Sphagnales is one of two oldest lineages separated from the main trunk of moss phylogenetic tree, it appears in fossil state regularly only since Late Cretaceous, ca.

Bryophytes of Azorean parks and gardens (I): “Reserva Florestal de Recreio do Pinhal da Paz” - São Miguel Island. Arquipelago. Life and Marine Sciences 37: 1 – 20. https://doi.org/10.25752/arq.23643 Historic urban parks and gardens are increasingly being considered as interesting refuges for a great number of species, including some rare taxa, otherwise almost absent from urban areas, such as many bryophytes and other biota that are not their main focus. After a bibliographic work, the "Reserva Florestal de Recreio do Pinhal da Paz" (RFR-PP), in São Miguel Island (Azores), stood out as one of the least studied areas of the region, without any bryophyte’ references. Thus, the aim of this study was to identify the most striking bryophyte species present along the main visitation track of RFR-PP, in order to increase its biodiversity knowledge. Bryophytes growing on rocks, soil or tree bark were collected ad- hoc, in 17 sites, ca. 100 m apart from each other. In total, 43 species were identified: 23 mosses, 19 liverworts, and one hornwort, encompassing five classes, 15 orders and 27 families. Seven species are endemic from Europe and three from Macaronesia. No invasive bryophytes were found in the surveyed area.

Box 7, FI-00014 University of Helsinki, Finland; Email: [email protected] (*corresponding author) 2Einsteinweg 2, P.O. Box 9514, 2300 RA Leiden, The Netherlands Abstract Neckera praetermissa Enroth & Touw spec. nov. (Neckeraceae) is described from northern Vietnam. It is morphologically closest to the SE Asian N. undulatifolia (Tix.) Enroth, with which it shares the similar, ovate-ligulate and symmetric leaves with coarsely dentate apices, and strongly incrassate and porose leaf cell walls. However, N. undulatifolia has the stems up to 10 cm long and a distinct costa reaching to 5/6 of leaf length, while the stems of N. praetermissa are to c. 3 cm long and the leaves are ecostate or with a weak costa reaching to 1/6 of leaf length at most. Key words: Taxonomy, Pleurocarpous mosses, New species, Tropics Introduction Based on genomic data, the systematics of the pleurocarpous moss family Neckeraceae has in the recent years undergone profound changes, reviewed by Enroth (2013). Olsson et al. (2009) showed that the family is divided into three well-supported clades that the authors called Neckera-clade, Thamnobryum-clade and Pinnatella-clade. At the genus level, several of the “traditional” genera, such as Porotrichum (Brid.) Hampe (1863: 154), Thamnobryum Nieuwland (1917: 50), Homalia Bridel (1827: xlvi, 325, 763, 807, 812), Pinnatella Fleischer (1906: 79), Neckera Hedwig (1801: 200–210) and Forsstroemia Lindberg (1863: 605) were shown to be poly- or paraphyletic, and as a result several new genera were erected (e.g.

  • Molecular Phylogeny of Chinese Thuidiaceae with Emphasis on Thuidium and Pelekium
    Molecular Phylogeny of Chinese Thuidiaceae with emphasis on Thuidium and Pelekium QI-YING, CAI1, 2, BI-CAI, GUAN2, GANG, GE2, YAN-MING, FANG 1 1 College of Biology and the Environment, Nanjing Forestry University, Nanjing 210037, China. 2 College of Life Science, Nanchang University, 330031 Nanchang, China. E-mail: [email protected] Abstract We present molecular phylogenetic investigation of Thuidiaceae, especially on Thudium and Pelekium. Three chloroplast sequences (trnL-F, rps4, and atpB-rbcL) and one nuclear sequence (ITS) were analyzed. Data partitions were analyzed separately and in combination by employing MP (maximum parsimony) and Bayesian methods. The influence of data conflict in combined analyses was further explored by two methods: the incongruence length difference (ILD) test and the partition addition bootstrap alteration approach (PABA). Based on the results, ITS 1& 2 had crucial effect in phylogenetic reconstruction in this study, and more chloroplast sequences should be combinated into the analyses since their stability for reconstructing within genus of pleurocarpous mosses. We supported that Helodiaceae including Actinothuidium, Bryochenea, and Helodium still attributed to Thuidiaceae, and the monophyletic Thuidiaceae s. lat. should also include several genera (or species) from Leskeaceae such as Haplocladium and Leskea. In the Thuidiaceae, Thuidium and Pelekium were resolved as two monophyletic groups separately. The results from molecular phylogeny were supported by the crucial morphological characters in Thuidiaceae s. lat., Thuidium and Pelekium. Key words: Thuidiaceae, Thuidium, Pelekium, molecular phylogeny, cpDNA, ITS, PABA approach Introduction Pleurocarpous mosses consist of around 5000 species that are defined by the presence of lateral perichaetia along the gametophyte stems. Monophyletic pleurocarpous mosses were resolved as three orders: Ptychomniales, Hypnales, and Hookeriales (Shaw et al.
