Летом 2017 г., в ходе таксономической ревизии Нижнего Дендросада СПбГЛТУ были обнаружены 2 экземпляра лжелиственницы Кемпфера (Pseudolarix amabilis), ранее числившихся под названием Larix potaninii Batalin.

    BIOL/APBI 324 – Introduction to Seed Plant Taxonomy

    This syllabus is a general representation of the course as previously offered and is subject to change. BIOL/APBI 324 – Introduction to Seed Plant Taxonomy General Course Syllabus (as of September 2019) About the Course: Course Description: An introduction to seed plant taxonomy emphasizing descriptive morphology and identification. Each student will be required to submit a plant collection. Correct understanding of the actual relationships between plants, rather than superficial resemblance, is the basis of comparative biology required to analyze the diversity of plant forms. The species diversity of plants is considerable, and this course will pay particular attention to very diverse and important groups such as the grasses and the orchids, focusing on reasons for their evolutionary success. Identification skills will be inculcated by the lectures working in tandem with the laboratory sessions. This course aims to give students a good working knowledge of plant taxonomy as a preparation for work in any biological discipline. Course Format: Lecture and Laboratory Credits: 3 Pre-requisites: BIOL 121 Course Learning Objectives: By the end of this course, students will be able to: • Achieve a good working knowledge of concepts, principles, and recent discoveries in plant taxonomy. • Gain an overview of seed plant diversity, including the most species-rich plant families and so be able to place any botanical information in the overall context of plant diversity. • Learn ways in which their knowledge can be applied to ecology and evolutionary biology. • Gain an appreciation of how current research in the field is being done by reading recent research papers. Textbooks and Additional Resources: Laboratory fee: $25; please bring to first lab.
  • Principles of Plant Taxonomy, V.*

    Principles of Plant Taxonomy, V.*

    THE OHIO JOURNAL OF SCIENCE VOL. XXVIII MARCH, 1928 No. 2 PRINCIPLES OF PLANT TAXONOMY, V.* JOHN H. SCHAFFNER, Ohio State University. After studying the taxonomy of plants for twenty-five years the very remarkable fact became evident that there is no general correspondence of the taxonomic system with the environment, but as the great paleontologist, Williams, said in 1895: "environmental conditions are but the medium through which organic evolution has been determinately ploughing its way." Of course, the very fact that there is a system of phylogenetic relationships of classes, orders, families, and genera and that these commonly have no general correspondence to environment shows that, in classifying the plant material, we must discard all notions of teleological, utilitarian, and selective factors as causative agents of evolution. The general progressive movement has been carried on along quite definite lines. The broader and more fundamental changes appeared first and are practically constant, and on top of these, .potentialities or properties of smaller and smaller value have been introduced, until at the end new factors of little general importance alone are evolved. These small potentialities are commonly much less stable than the more fundamental ones and thus great variability in subordinate characters is often present in the highest groups. We must then think of the highest groups as being full of hereditary potentialities while the lower groups have comparatively few. As stated above, there is a profound non-correspondence of the .taxonomic system and the various orthogenetic series with the environment. The system of plants, from the taxonomic point of view, is non-utilitarian.

We detected intraspecific variation for possible candidate cpDNA markers in Japanese larch. Background and Objectives: The natural distribution of Japanese larch is limited to the mountainous range in the central part of Honshu Island, Japan, with an isolated northern limit population (Manokami larch). In this study, we determined the phylogenetic position of Manokami larch within Japanese larch, characterized the chloroplast genome of Japanese larch, detected intraspecific variation, and determined candidate cpDNA markers. Materials and Methods: The complete genome sequence was determined for eight individuals, including Manokami larch, in this study.

This botanical treasure trove is under growing pressure from a complex chain of cause and effect of unprecedented magnitude: demographic, socio-economic and climatic changes, habitat conversion and loss, unsustainable use of native species and introduction of exotic ones, together with environmental contamination are rapidly transforming China’s ecosystems. There is a steady rise in the number of plant species that are on the verge of extinction. Great Wall, Badaling, Beijing (Image: Zhang Qingyuan) Botanic Gardens Conservation International (BGCI) therefore seeks to assist China in its endeavours to maintain and conserve the country’s extraordinary botanical heritage and the benefits that this biological diversity provides for human well-being. It is a challenging venture and represents one of BGCI’s core practical conservation programmes.

To examine the biogeographic history of Tsuga, phylogenetic relationships among multiple accessions of all nine species were inferred using chloroplast DNA sequences and multiple cloned sequences of the nuclear ribosomal ITS region. Analysis of chloroplast and ITS sequences resolve a clade that includes the two western North American species, T. heterophylla and T. mertensiana, and a clade of Asian species within which one of the eastern North American species, T. caroliniana, is nested. The other eastern North American species, T. canadensis, is sister to the Asian clade. Tsuga chinensis from Taiwan did not group with T.
