This book was released on 1976 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study is made of the tribe Gesnerieae of the family Gesneriaceae from the West Indies, giving information on history, anatomy and morphology, pollination and dispersal, and hybridization in the tribe. The tribe comprises 67 species in 3 genera: Rhytidophyllum, Gesneria, and Pheidonocarpa. The last genus is described as new, with a new species combination, Pheidonocarpa corymbosa (Swartz) L. Skog, and 2 subspecies. A revision of Gesneria Linnaeus is presented based on field and herbarium studies. Gesneria is divided into 9 sections, 46 species (a new species, Gesneria onychocalyx L. Skog, is described), 12 subspecies, and 11 varieties. The taxonomic portion includes keys, synonymies, descriptions, typifications, distributions, and ecology, as well as distribution maps and illustrations of the taxa. Also enumerated in Appendix 1 are many species names once included in Gesnera or Gesneria, but which have been transferred to other genera. Two new combinations are made in this portion of the text: Rhytidophyllum cumanense (Hanstein) L. Skog and Rhytidophyllum onacaense (Rusby) L. Skog.

Book excerpt: The components of the vascular systems in the male floret and the female floret of Raddia are described from reconstructed serial, transverse sections. Squat tracheary elements, sieve elements, and intermediary cells comprise the systems. The male floret has six and the female floret three collateral bundles in the rachilla at the floret base that become interconnected into a lower sieve-element plexus with accompanying tracheary elements. Besides contributing to the lower plexus, the rachilla bundles serve as the traces for the lemma and palea. That bundle (bundle 3) which is the trace for the lemma median contributes most of the sieve and tracheary elements to the lower plexus. Supernumerary bundles are associated with bundle 3. Rising in the rachilla from the lower plexus is the upper plexus of sieve and tracheary elements. The circular form of the upper plexus of the male floret is influenced by the two traces from each of the anterior lodicules and by each trace from the three stamens. The trace from the posterior lodicule of the male and female florets does not influence the upper plexus. The bi-arcuate form of the upper plexus of the female floret is influenced by the two, more posterior traces from the anterior lodicules. The three staminodia in the female floret do not influence the upper plexus because they are avascular. At the pistil base is a massive amphicribral bundle, the pistil plexus, that sends down vascular prongs and lobes to merge with the upper and lower plexi. Two posterolateral (stylar) collateral bundles merge with the pistil plexus in a gynobasic manner. A placental bundle ascends from the posterior of the pistil plexus, merges with the chalaza, and exceeds the tip of the ovule before ending in a stylar core. Components of the floret vascular system of Raddia confirm the Olyreae as a tribe of the Bambusoideae that should not be placed in the subfamilies Festucoideae, Oryzoideae, or Panicoideae.

Available in PDF, EPUB and Kindle. Book excerpt: Armen Takhtajan is among the greatest authorities in the world on the evolution of plants. This book culminates almost sixty years of the scientist's research of the origin and classification of the flowering plants. It presents a continuation of Dr. Takhtajan’s earlier publications including “Systema Magnoliophytorum” (1987), (in Russian), and “Diversity and Classification of Flowering Plants” (1997), (in English). In his latest book, the author presents a concise and significantly revised system of plant classification (‘Takhtajan system’) based on the most recent studies in plant morphology, embryology, phytochemistry, cytology, molecular biology and palynology. Flowering plants are divided into two classes: class Magnoliopsida (or Dicotyledons) includes 8 subclasses, 126 orders, c. 440 families, almost 10,500 genera, and no less than 195,000 species; and class Liliopsida (or Monocotyledons) includes 4 subclasses, 31 orders, 120 families, more than 3,000 genera, and about 65,000 species.This book contains a detailed description of plant orders, and descriptive keys to plant families providing characteristic features of the families and their differences.

Download or read book Flowering Plants Dicotyledons written by Joachim W. Kadereit and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, 24 flowering plant families comprising a total of 911 genera are treated. They represent the asterid order Lamiales except for Acanthaceae (including Avicenniaceae), which will be included in a later volume. Although most of the constituent families of the order have been recognized as being closely related long ago, the inclusion of the families Byblidaceae, Carlemanniaceae and Plocospermataceae is the result mainly of recent molecular systematic research. Keys for the identification of all genera are provided, and likely phylogenetic relationships are discussed extensively. To facilitate the recognition of relationships, families are cross-referenced where necessary. The wealth of information contained in this volume makes it an indispensable source for anybody in the fields of pure and applied plant sciences.

Available in PDF, EPUB and Kindle. Book excerpt: Seeds are a vital part of life on earth. They are fundamental for plant reproduction, and many seeds play an important role in the diet of man and domestic and wild animals. Knowledge of the appearance of seeds - seed morphology - is of great importance to botany and seed identification in relation to: seed setting, quarantine work, forensic work, seed poisening, studies of seed dispersal, seed banks and archaeological studies.;This bibliography contains 3775 references and is divided in two parts: handbooks, and articles and monographs. In the latter the bibliographical reference is supplemented by information of importance to seed identificaiton: genera mentioned in articles, keys, descriptions, drawings, photograph, scanning electron micrographs, anatomy and chemical methods. The index of authors contains the names of an extensive number of authors, cited in the bibliography, and in the index of genera more than 3900 genera, described in one or more of the publications are cited.
