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).
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.
Download or read book Flowering Plants written by Armen Takhtajan and published by Springer Science & Business Media. This book was released on 2009-07-06 with total page 906 pages. 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 The Alkaloids written by M F Grundon and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued.

Download or read book The Trees of Florida written by Gil Nelson and published by Rowman & Littlefield. This book was released on 2023-03-02 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the first comprehensive guide to Florida's amazing variety of tree species: from scrub oak on the high central ridges to mangroves stretching along the southern coasts, from mighty live oaks to the delicate and diminutive hawthornes, from bald cypress with their knees poking up from the swamps to the coppery-colored gumbo limbo found in tropical hammocks of the Everglades and Keys, from the sabal palm found all over the state to the rare and endangered yew found only along the banks of the Apalachicola River in northern Florida. Florida, unique among the states, has both tropical and temperate forests. The early Florida visitor was awed by miles of unending pine flatwoods. Most modern Florida visitors are amazed by the lush tropical trees planted in cities, suburbs, and public gardens. This book covers both natives and exotics and includes suggested field sites for observing the species described. Divided into two sections, this book serves as both a reference and a field guide. Both sections help the reader answer the question “What tree is that?" by focusing on the families of Florida's trees. The line drawings show a combination of typical leaves, fruits, and flowers, and while accurate in detail, capture an overall impression, so helpful when trying to identify a species in the field. The color photos, all taken in Florida, are useful where color is important in identification. The first edition was very popular with both professionals and laypeople alike—it was heralded as accurate, comprehensive, and organized and written in an easy-to-understand way. This edition will be even more useful, as it adds about 140 more tree accounts for a total of more than 480 species. There are almost 600 color photos and many drawings and range maps. And now included is a key to tree families that will help with field identification.
Download or read book Natural Products of Woody Plants written by John W. Rowe and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.
