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.

Available in PDF, EPUB and Kindle. Book excerpt: The CRC Ethnobotany Desk Reference contains almost 30,000 concise ethnobotanical monographs of plant species characteristics and an inventory of claimed attributes and historical uses by cultures throughout the world-the most ambitious attempt to date to inventory plants on a global scale and match botanical information with historical and current uses.To obtain the same information about any species listed, you would have to thumb through hundreds of herbal guides, ethnobotanical manuals, and regional field guides. Sources for this index include the three largest U.S. Government ethnobotany databases, the U.S. National Park Service NPFlora plant inventory lists, and 18 leading works on the subject.

Download or read book A Phylogenetic Monograph of Mentzelia Section Bartonia Loasaceae written by John J. Schenk and published by . This book was released on 2020-12-18 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mentzelia sect. Bartonia (Loasaceae) is the most species-rich of the six sections of Mentzelia. The section consists of overwintering annuals, biennials, and short- to long-lived, sometimes subshrubby perennials whose geographic ranges are centered primarily in western North America. Synapomorphies that support its monophyly include winged seeds that are horizontally positioned in capsules, seed testal microsculpture consisting of straight, wavy, or sinuate anticlinal cell walls with 4-106 papillae per cell, and broadened filaments (without distal flanges) on the outermost stamens positioned opposite the sepal lobes. Monophyly of the section is well supported by molecular characters from plastid and nuclear DNA. Despite the distinctiveness of species in sect. Bartonia from those of other sections, patterns of variation within the section have led to taxonomic difficulties that have obscured our understanding of diversity within the section. We applied a phylogenetic approach with DNA sequence data, sampled widely across geographic and taxic entities, including multiple populations of putatively morphologically variable and geographically disjunct species, to assess partitioning of morphological diversity among lineages in sect. Bartonia. We identified two major lineages that diverged early in sect. Bartonia. The first lineage, clade 1, includes M. multiflora, M. humilis, M. pumila, M. laevicaulis, and relatives. The second lineage, clade 2, includes M. decapetala, M. multicaulis, M. argillosa, and relatives, many of which are subshrubby, short-lived perennial species centered geographically in the intermountain West. The lineages we reconstructed served as a basis for taxonomic revision, and our results are consistent with the recognition of 51 species, including three with varieties. This number of species is nearly twice that recognized in earlier Mentzelia monographs. Types are reviewed, and names are lectotypified as necessary. Character synopses, including taxonomically critical seed microsculpture data and floral petal and stamen shape series, distribution maps, conservation status, and taxonomic keys (including a separate key to the eight taxa that occur in Mexico) are provided for thespecies and varieties.

Download or read book Plants of British Columbia written by Hong Qian and published by UBC Press. This book was released on 1998 with total page 552 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an up-to-date checklist of the current valid taxonomyfor all vascular plants, bryophytes, and lichens in British Columbia,including synonyms, species codes, and other information. A convenient,geographically restricted, comprehensive checklist like this one willaid greatly in avoiding the present confusion concerning the names ofmany species in the ecological and systematic literature, as well as inapplied fields. The book is organized into three sections. Part 1 organizes speciesalphabetically according to taxonomic order by families of vascularplants, bryophytes, and lichens. Within each family, the genera arelisted alphabetically, along with any synonomies (former names) andcommon names. In Part 2 species are organized alphabetically accordingto their scientific names. Part 3 lists common names followed by theirscientific names. Excluded names (names inappropriately applied toplants in B.C.) are given in an appendix. Those familiar with planttaxonomy will find Part 1 particularly helpful when checkingnomenclature; semi-professionals familiar with scientific names willuse Part 2 and then Part 1; those who know only common names will checkPart 3 and then Part 2 and Part 1 to determine families. There is presently considerable confusion about many species namesin B.C. Plant names change for many reasons and new plants invade.Information about plants in B.C. is scattered in several checklists,most of them incomplete or out of date; for some species, such asliverworts, no provincial checklist even exists. This checklisttherefore will be useful to all professionals working with vegetationand for students in agriculture, botany, ecology, forestry and othersciences. Although the focus is on B.C., the book will also be usefuloutside the province, particularly in the northwest American states andin Alberta and the Yukon.

Download or read book Comparative Embryology of Angiosperms Vol 1 2 written by Brij M. Johri and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 1243 pages. Available in PDF, EPUB and Kindle. Book excerpt: COMPARATIVE EMBRYOLOGY OF ANGIOSPERMS is a review of the developmental processes leading to sexual reproduction in flowering plants. On the basis of embryological data and certain evidences from other areas of study, it lays special emphasis on the relationship among and within the families and orders of angiosperms. Occasionally, inaccuracies in observation and interpretation are pointed out, alternative interpretations offered, gaps in our knowledge highlighted, and prospects outlined. The text is documented with 36 tables, 376 figures, and about 5000 literature citations, which contribute to making this book comprehensive. Besides students and research workers interested in angiosperm embyology, taxonomists, plant breeders, agriculturists, and horticulturists will also find much useful information in this treatise.
