ACTA BOTA ICA FENNICA 89 EDIDIT SOCIETAS PRO FAUNA ET FLORA FEN ICA DILLENIUS 'S ' HISTORIA MUSCORUM' AS THE BASIS OF HEPATIC NOMENCLATURE, AND S. 0. LINDBERG'S COLLECTION OF DILLENIAN BRYOPHYTES BY PEKKA ISOVIITA BOTANICAL MUSEUM, UN IVERSITY OF HELSINKI HELSI KI-HELSI GFORS 1970 Acta Bot. Fennica 89. 28 pp. Nov. 1970 PR1NTED BY TlLG:uA.'-'N HELSINK1-HELSINGFORS 1970 Abstract The principles and different possibilities involved in the typification of Linnaeus's specific names of Hepaticae are discussed. Dillenius's 'Historia muscorum' appears to be the foremost source of Linnaeus's Hepaticae species, and thus Dillenius's herbarium of the 'Historia muscorum' usually forms the best basis for the typification of the names given to them by Linnaeus. Linnaeus's own material was fairly limited, and only a few names can be typified from his herbarium. The neglected collection of Dillenius's speci­ mens of Hepaticae in the herbarium of S. 0. Lindberg in Helsinki is presented, and a comprehensive !ist is given of specific names whose protologues contain a reference to a Dillenian species of Hepaticae. Same nomenclatural problems of Hepaticae are mentioned. Lindberg's collection of Dillenius's specimens of :\fusci is also presented. Contents I. Introduction II.

Isov_iita: Dillenius's 'Historia muscorum· I. lntroduction In the early cryptogamic taxonomy the publication of J. J. DILLENrus's 'Historia muscorum' in 1741 was one of the most epoch-making events. 'The thorough descriptions and the 85 copperplates - each containing numerous figures - of this quarto-sized monograph were regularly used and cited by students of cryptogams up till the early 1800's. Even today it is an important nomendatural source. The plant collection on which DILLENIUS mainly based his illustrations and descriptions is still at the Department of Botany of the University of Oxford (OXF). Several investigations have been made on the mosses, liverworts and lichens of this herbarium of 'Historia muscorum'. Regarding the bryophytes, the profound revision by S. 0. LINDBERG (1883; see also LINDBERG 1874, 1877) deserves particular mention (for lichens, see CRoMEIE 1880). In his taxonomic and nomendatural investigations of bryophytes, LIND­ BERG showed special interest in clarifying the early phases of this field of research, and published several valuable papers on this subject. As a conse­ quence of these studies, LINDBERG's herbarium (H-SOV, Botanical Museum of the University of Helsinki), which is known tobe rich in the specimens of contemporary bryologists, contains also specimens of many of the pioneers, e.g., A. BuDDLE, S. VAILLANT, F. EHRHART, J. DICKSON, 0. SwARTZ, H . A. ScHRADER, J. C. SCHLEICHER, and G. WAHLENBERG. The Dillenian bryophyte collection was studied by I,INDBERG in Oxford in 1872. He very well knew the particular importance of this collection and with deep gratitude reported that M. A. LAWSON, Sherardian Professor of Botany in Oxford, had permitted him to take with him small pieces of DILLENrus's specimens, for their critical identification in Helsinki (LrNDBERG 1877:14, 1883:10). He, however, failed to mention that he had carefully preserved these small samples and arranged them as a special collection. After the death of LINDBERG in 1889, hisherbariumwas purchased by the University of Helsinki, and the small but valuable collection of Dillenian spec­ imens was specially mentioned (SAELAJ-< et al. 1890:6) in connection with this transaction. Nevertheless, for nearly 80 years from that date no information regarding these specimens was available, and they were totally forgotten and neglected, until the collection was found fairly recently among the material of LINDBERG at the Botanical Museum of the University of Helsinki. It was in the same excellent condition as it was left by LINDBERG himself, and this dis­ covery led to the present study, whose aim is to assess the nomenclatural im­ portance of DILLENius's 'Historia muscorum' and herbarium specimens. 1 S. 0. LINDBERG's bryophyte herbarium is kept as a separate collection. Its abbrevia­ tion, H-SOL, will be mentioned in the neJ.:t edition of 'Index herbariorum'. ACTA BOTANICA FENNICA 89 5 li. Linnaeus's 'Species plantarum' as the starting point of the nomenclature of Hepaticae, and the importance of Dillenius's 'Historia muscorum' In cantrast to the situation with many other cryptogam groups, LrNNAEus's 'Species plantarum' (1753) has been ruled as the ;nomenclatural starting point of the Hepaticae. However, this decision does not in any way mean that LINNAEUS should be regarded as more of a specialist in hepatics than, for example, in mosses. In this connection, it is not possible or necessary to discuss in detail the descriptive method of LrKNAEUS and the general principles of the typification of the specific names published

  • Chemical Constituents of 25 Liverworts
    J. Hattori Bot. Lab. No. 74: 121- 138 (Nov. 1993) CHEMICAL CONSTITUENTS OF 25 LIVERWORTS 1 1 TOSHIHIRO HASHIMOT0 , YOSHINORI ASAKAWA , KATSUYUK.l NAKASHIMA1 AND MOTOO Toru1 ABSTRACT. Twenty-five liverworts were investigated chemically and 20 new compounds isolated and their structures characterized by spectroscopic evidence, X-ray analysis and chemical correlation. The chemosystematics of each species is discussed. INTRODUCTION Liverworts are rich sources of terpenoids and lipophilic aromatic compounds; these are very valuable for chemosystematic investigation. Previously, we have reported the chemical constituents of 700 species of liverworts and discussed the chemosystematics at family and genus level (Asakawa l 982a, b; 1993, Asakawa & Inoue l 984a; l 987a). Here we report the isolation and distribution of the terpenoids and aromatic compounds of 25 liverworts and discuss the chemical markers of each species. EXPERJMENTALS The liverworts collected in Japan and other countries shown in Table 1, were purified and dried for 1 to 7 days and then ground mechanically and extracted with ether or methanol for 7 to 30 days. Each extract was filtered and the solvent evaporated to give green crude oils, followed by chromatography on silica gel or Sephadex LH-20, using n­ hexane-ethyl acetate (EtOAc) and methanol-chloroform (1 : 1), respectively. Each fraction was further purified by a combination of preparative TLC (n-hexane-EtOAc 4 : 1) and preparative HPLC (µ.porasil; n-hexane-EtOAc 2 : 1). The stereostructures were elucidated by the analysis of spectroscopic data (UV, IR, MS, NMR and CD) and X-ray analysis or chemical correlation. The stereostructures of each compound characterized by the above methods are shown in Chart 1 and the structural elucidation of the new compounds will be reported elsewhere.

  • About the Book the Format Acknowledgments
    About the Book For more than ten years I have been working on a book on bryophyte ecology and was joined by Heinjo During, who has been very helpful in critiquing multiple versions of the chapters. But as the book progressed, the field of bryophyte ecology progressed faster. No chapter ever seemed to stay finished, hence the decision to publish online. Furthermore, rather than being a textbook, it is evolving into an encyclopedia that would be at least three volumes. Having reached the age when I could retire whenever I wanted to, I no longer needed be so concerned with the publish or perish paradigm. In keeping with the sharing nature of bryologists, and the need to educate the non-bryologists about the nature and role of bryophytes in the ecosystem, it seemed my personal goals could best be accomplished by publishing online. This has several advantages for me. I can choose the format I want, I can include lots of color images, and I can post chapters or parts of chapters as I complete them and update later if I find it important. Throughout the book I have posed questions. I have even attempt to offer hypotheses for many of these. It is my hope that these questions and hypotheses will inspire students of all ages to attempt to answer these. Some are simple and could even be done by elementary school children. Others are suitable for undergraduate projects. And some will take lifelong work or a large team of researchers around the world. Have fun with them! The Format The decision to publish Bryophyte Ecology as an ebook occurred after I had a publisher, and I am sure I have not thought of all the complexities of publishing as I complete things, rather than in the order of the planned organization.

O. Box 299, St. Louis, MO 63166–0299 U.S.A.; [email protected] Abstract A widely accessible list of known plant species is a fundamental requirement for plant conservation and has vast applications. An index of published names of liverworts and hornworts between 2009 and 2010 is provided as part of a continued effort in working toward producing a world checklist of this group. Included in the list are also names overlooked by earlier indices. The list includes 30 higher taxa, 250 species, 52 infraspecific taxa, 31 autonyms, and two fossils for 2009 and 2010. A number of taxa not covered by the earlier indices for 2000-2008 are also included. Key words: Liverworts, hornworts, index, nomenclature Introduction Under the auspices of the Early Land Plants Today project, there has been a strong community-driven effort attempting to address the critical need to synthesize the vast nomenclatural, taxonomic and global distributional data for liverworts (Marchantiophyta) and hornworts (Anthocerotophyta) (von Konrat et al. 2010a). These endeavours are critical in providing the foundation to develop a working checklist of liverworts and hornworts worldwide; the first version is projected to be published in 2012.

These partnerships are thought to have propelled plant terrestrialisation some 500 million years ago and today they play major roles in ecosystem functioning. It has long been known that bryophytes harbour, in their living tissues, fungal symbionts, recently identified as belonging to the three mycorrhizal fungal lineages Glomeromycotina, Ascomycota and Basidiomycota. Latest advances in understanding of fungal associations in bryophytes have been largely driven by the discovery, nearly a decade ago, that early divergent liverwort clades, including the most basal Haplomitriopsida, and some hornworts, engage with a wider repertoire of fungal symbionts than previously thought, including endogonaceous members of the ancient sub-phylum Mucoromycotina.
