For many years orchids have been among the most popular of ornamental plants, with thousands of species and hybrids cultivated worldwide for the diversity, beauty, and intricacy of their flowers. This book is the eagerly-awaited result of over 30 years of research into orchid anatomy by one of the world's leading authorities and is the first comprehensive publication on orchid anatomy since 1930. It describes the structure and relationships among the cells and tissues of leaves, stems, and roots, and is organized systematically in line with the taxonomy expressed in the OUP Genera Orchidacearum Series. The book is fully illustrated with over 100 photomicrographs and numerous original line drawings. This latest addition to the Anatomy of the Monocotyledons Series is an essential reference text for orchid scientists and research students and will also be of interest and use to a broader audience of orchid enthusiasts.
An anatomical and comparative study of the monocotyledonous group of flowering plants, first published in 1925.
In the 2007 third edition of her successful textbook, Paula Rudall provides a comprehensive yet succinct introduction to the anatomy of flowering plants. Thoroughly revised and updated throughout, the book covers all aspects of comparative plant structure and development, arranged in a series of chapters on the stem, root, leaf, flower, seed and fruit. Internal structures are described using magnification aids from the simple hand-lens to the electron microscope. Numerous references to recent topical literature are included, and new illustrations reflect a wide range of flowering plant species. The phylogenetic context of plant names has also been updated as a result of improved understanding of the relationships among flowering plants. This clearly written text is ideal for students studying a wide range of courses in botany and plant science, and is also an excellent resource for professional and amateur horticulturists.
A comprehensive discussion of the vegetative anatomy of orchids, describing the structure and relationships among the cells and tissues of leaves, stems, and roots.
This aesthetically unique book combines ecological, morphological and anatomical, as well as phylogenetic studies on plant material in a largely unexplored dry mountain region above the timberline. It offers the first comparative analysis of hundreds of plants - annuals, perennial herbs and dwarf shrubs - in an area of 87,000 km2 at altitudes from 2600 to 6150 m above sea level in the Western Himalaya. Characteristic landscape pictures of all major vegetation types and maps show at which locations and altitudes the individual species of vascular plants are distributed, while macroscopic plant pictures and plant age are related to high-quality micro-sections and micro-photographs. The anatomical features of 345 dicotyledons were characterized using the published coding systems and those of 155 monocotyledones were characterized on the basis of a newly developed key. The number of annual rings and anatomical features of the xylem and phloem of dicots are compared and related to different ecological conditions within this extremely dry and cold environment. The ecological and anatomical characterization is used to create a phylogenetic tree based on nucleotide sequences, and indicates which features are genetically stable and which ones are modified by environmental factors. The book appeals to scientists in the fields of plant taxonomy, morphology, anatomy and ecology.
In this volume treatments are offered for 52 families containing 432 genera belonging to 13 eudicot orders, many of which have recently been newly designed; four families remain unassigned to order. Emphasis is on the early-diverging eudicots and basal core eudicots. The wealth of information contained in this volume will make it an important source of reference for both the scholar and the practitioner in the fields of pure and applied plant sciences.
Contemporary Problems in Plant Anatomy contains the proceedings of a plant anatomy symposium that took place at Duke University and The University of North Carolina at Chapel Hill in 1983. The symposium addressed challenges in four basic research areas in contemporary plant anatomy: leaf development, floral development, differentiation of cells and tissues, and systematic and ecological anatomy. The book highlights new techniques and approaches for dealing with problems in each of these areas. Organized into 12 chapters, this volume begins with an overview of the stem-conducting tissues in monocotyledons; the development of vascular tissue patterns in the shoot apex of ferns; the role of subsidiary trace bundles in stem and leaf development of the dicotyledoneae; and the structure of phloem. It then discusses the cellular parameters of leaf morphogenesis in maize and tobacco; alternative modes of organogenesis in higher plants; morphological aspects of leaf development in ferns and angiosperms; the origin of symmetry in flowers; and intraspecific floral variation. The reader is also introduced to structural correlations among wood, leaves, and plant habit; relationships between structure and function in trees; and the development of inflorescence, androecium, and gynoecium with reference to palms. This book is a valuable source of information for plant anatomists.
This volume is the outcome of a modern phylogenetic analysis of the grass family based on multiple sources of data, in particular molecular systematic studies resulting from a concerted effort by researchers worldwide, including the author. In the classification given here grasses are subdivided into 12 subfamilies with 29 tribes and over 700 genera. The keys and descriptions for the taxa above the rank of genus are hierarchical, i.e. they concentrate upon characters which are deemed to be synapomorphic for the lineages and may be applicable only to their early-diverging taxa. Beyond the treatment of phylogeny and formal taxonomy, the author presents a wide range of information on topics such as the structural characters of grasses, their related functional aspects and particularly corresponding findings from the field of developmental genetics with inclusion of genes and gene products instrumental in the shaping of morphological traits (in which this volume appears unique within this book series); further topics addressed include the contentious time of origin of the family, the emigration of the originally shade-loving grasses out of the forest to form vast grasslands accompanied by the switch of many members to C4 photosynthesis, the impact of herbivores on the silica cycle housed in the grass phytoliths, the reproductive biology of grasses, the domestication of major cereal crops and the affinities of grasses within the newly circumscribed order Poales. This volume provides a comprehensive overview of existing knowledge on the Poaceae (Gramineae), with major implications in terms of key scientific challenges awaiting future research. It certainly will be of interest both for the grass specialist and also the generalist seeking state-of-the-art information on the diversity of grasses, the most ecologically and economically important of the families of flowering plants.
Monocots: Systematics and Evolution presents leading work from around the world on non-grass monocotyledons and includes reviews and current research into their comparative biology, phylogeny and classification. The papers are based on presentations at the Second International Conference on the Comparative Biology of the Monocotyledons, Monocots II, held in Sydney, Australia in late 1998. Many were subsequently updated or extended to take into account new information. All 72 papers have been peer-reviewed.
