Download or read book The Genus Diplusodon Lythraceae written by Taciana Barbosa Cavalcanti and published by Springer Nature. This book was released on 2022-03-06 with total page 522 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is a monograph of the genus Diplusodon (Lythraceae), written by the world authority on this plant group. Diplusodon is a monophyletic genus of shrubs and subshrubs, with showy, 6-merous, actinomorphic flowers, and floral tubes on which the sepals alternate with conspicuous epicalyx segments. The capsular fruit contains winged seeds and, uniquely for the family, is divided by a bipartite placenta with two semi-lunate septa. Diplusodon is the second largest genus in the Lythraceae and occurs mostly in the Cerrado Biome, the floristically diverse savannah that covers more than two million km2 of the Central Brazilian Plateau, extending west into Bolivia, south to Paraguay and east to the Caatinga. A total of 104 species and eight varieties are recognized in the genus, for which 46 lectotypes, one neotype, one new status and one new combination are designated, nine new species are described, and 15 taxa are placed in synonymy. New information on floral and vegetative morphology, pollen, cytology, chemistry, floral biology, and habitat are provided for the genus. In addition, keys to the species are accompanied by descriptions, illustrations, distribution maps, and assignment of conservation status.

Download or read book Diversity and Classification of Flowering Plants written by Armen Leonovich Takhtadzhi͡an and published by Columbia University Press. This book was released on 1997 with total page 662 pages. Available in PDF, EPUB and Kindle. Book excerpt: The culmination of more than fifty years of research by the foremost living expert on plant classification, Diversity and Classification of Flowering Plants is an important contribution to the field of plant taxonomy. In the last decade, the system of classifying plants has been thoroughly revised. Instead of describing every individual family, Takhtajan includes descriptions in keys to families, which he calls "descriptive keys." The advantage of descriptive keys is that they give both the characteristic features of the families and their differences. The delimitation of families and orders drastically differs from the one accepted by the Englerian school and from the one accepted in Arthur Cronquist's system. Takhtajan favors the smaller, more natural families and orders, which are more coherent and better-defined, where characters are easily grasped, and which are more suitable for information retrieval and phylogenetic studies, including cladistic analysis (because it reduces polymorphic codings).

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 A Revision of Cuphea Section Melvilla Lythraceae written by Shirley A. Graham and published by . This book was released on 2019-01-08 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Revision of Cuphea sect. Melvilla provides the first study of the section since the monograph by Emil Koehne in 1903 and is part of an on-going revision of the approximately 250 species constituting this New World genus. The section, with six subsections, is one of 13 in Cuphea. It consists of perennial herbs to small shrubs with large, intensely colored floral tubes mostly more than 20 mm long. The species are distributed from northwestern Mexico and the Caribbean to northern Argentina in locally moist or wet habitats. Forty-two species and four varieties are treated, an increase from the 27 species originally recognized in the section. The species are restricted either to North America (including Central America and the Caribbean): 23 spp. in two subsections; or to South America: 19 spp. in three subsections. Separate keys are presented for the species of each continent. Species descriptions, accounts of pollen and seed morphology, illustrations, and distribution maps are provided. Chromosome numbers and seed oil composition data are given for many species. Cuphea setifera S.A.Graham from Mexico is described as new. Lectotypes are designated for three subsections of sect. Melvilla and for C. bracteolosa, C. caeciliae, C. cuiabensis, C. grandiflora, C. heydei, C. hybogyna, C. intermedia, C. micropetale var. hirtella, C. niederleinii, C. paradoxa, C. subuligera, and C. watsoniana. Neotypes are designated for C. ignea, C. melvilla, and C. schumannii. Relationships suggested by morphology are compared to results from recent molecular-based phylogenetic studies of Cuphea. Twenty-seven of the 42 species of sect. Melvilla compose six informal groups of species based on unique suites of morphological characters. They correspond in part to two of the original six subsections. The remaining 15 species combine character states in diverse combinations that do not sort into groups or lineages. The molecular studies indicate that sect. Melvilla is polyphyletic and characterized by extensive homoplasy. Members of sect. Melvilla are distributed in three of the five major clades of the genus. Within the section, increases in flower size, intensity of the floral tube and petal color, and pollinator reward, appear to have evolved together with attraction of large bee and hummingbird pollinators. The present infrasectional classification of sect. Melvilla is not accepted. A new classification of species currently in the section in expected upon completion of the revision of the genus.

Download or read book Aquatic Dicotyledons of North America written by Donald H. Les and published by CRC Press. This book was released on 2017-09-01 with total page 3174 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aquatic Dicotyledons of North America: Ecology, Life History, and Systematics brings together a wealth of information on the natural history, ecology, and systematics of North American aquatic plants. Most books on aquatic plants have a taxonomic focus and are intended primarily for identification. Instead, this book provides a comprehensive overview of the biology of major aquatic species by compiling information from numerous sources that lie scattered among the primary literature, herbarium databases, and other reference materials. Included dicotyledon species are those having an obligate (OBL) wetland status, a designation used in the USACE National Wetland Plant List. Recent phylogenetic analyses are incorporated and rationale is provided for interpreting this information with respect to species relationships. This diverse assemblage of information will be useful to a wide range of interests including academic researchers, wildlife managers, students, and virtually anyone interested in the natural history of aquatic and wetland plants. Although focusing specifically on North America, the cosmopolitan distribution of many aquatic plants should make this an attractive text to people working virtually anywhere outside of the region as well. This book is an essential resource for assisting with wetland delineation.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents light microscopic anatomical images of aquatic and wetland plant stem. It features double-stained cross- and longitudinal sections of almost 400 species of vascular plants from the lowland to the alpine zone in Central Europe, including plants from lakes, ponds, rivers, bogs, fens, wet meadows, saline meadows, tall herb associations and alpine snow beds. The microscopic photographs at various magnifications are supplemented with detailed anatomical descriptions. For each species it provides a photo of the whole plant, a short morphological and ecological description as well as indications about its world- and Central European distribution. The book includes a hydrobotanical and an anatomical section. The hydrobotanical section describes the ecological classification of aquatic and wetland plants and explains major ecophysiological processes e.g., photosynthesis, mineral nutrition, gas exchange, adaptations to soil anoxia, turion formation and ecology. The anatomical section highlights the variety of structures and anatomical features of vascular plants in all wet environments.

This book was released on 2011-03-18 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work, published in two volumes, contains descriptions of the wood and bark anatomies of 3000 dicotyledonous plants of 120 families, highlighting the anatomical and phylogenetic diversity of dicotyledonous plants of the Northern Hemisphere. The first volume principally treats families of the Early Angiosperms, Eudicots, Core Eudicots and Rosids, while the second concentrates on the Asterids. Presented in Volume 1 are microsections of the xylem and phloem of herbs, shrubs and trees of 1200 species and 85 families of various life forms of the temperate zone along altitudinal gradients from the lowland at the Mediterranean coast to the alpine zone in Western Europe. The global perspective of the findings is underlined by the analysis of 500 species from the Caucasus, the Rocky Mountains and Andes, the subtropical zone on the Canary Islands, the arid zones in the Sahara, in Eurasia, Arabia and Southwest North America, and the boreal and arctic zones in Eurasia and Canada. The presence of annual rings in all life forms demonstrates that herbs and dwarf shrubs are an excellent tool for the reconstruction of annual biomass production and the interannual dynamic of plant associations. The common principle of the anatomical expression of secondary growth is a key factor in understanding evolution and adaptation processes in all life forms, from the 2 cm tall whitlow grass (Draba arctica) in the arctic to the 40 m tall beech (Fagus sylvatica) in Central European managed forests. The study opens vast fields of research for dendrochronology, wood anatomy, taxonomy and ecology.
