A comprehensive introduction to vascular plant phylogeny, the third edition of "Plant Systematics" reflects changes in the circumscription of many orders and families to represent monophyletic groups, following the most recent classification of the Angiosperm Phylogeny Group. Molecular taxonomic methods are fully presented, as are the results of many recent studies, both molecular and morphological.
"This book catalogs every plant found in J.R.R. Tolkien's Legendarium, showing how these plants influenced Tolkien's stories and characters"--
Incorporating phylogenetic principles and methods throughout, this text moves from the careful explanation of phylogenetic methods and principles to the taxonomic survey of vascular plant families. A much expanded CD-ROM is included, containing over 2,200 colour photos illustrating the diagnostic characters of plant families covered in the text. Appropriate for any course devoted to the systematics of plants, this text assumes no prerequisites other than introductory botany or biology.
A comprehensive introduction to vascular plant phylogeny, the Fourth Edition of Plant Systematics reflects changes in the circumscription of many orders and families to represent monophyletic groups, following the most recent classification of the Angiosperm Phylogeny Group. The taxonomic evidence described includes data from morphology, anatomy, embryology, chromosomes, palynology, secondary plant compounds, proteins, and DNA. Molecular taxonomic methods are fully presented, as are the results of many recent studies, both molecular and morphological. A chapter on the history of plant classification puts current systematic methods into historical context. Issues relating to variation in plant populations and species, including speciation and species concepts, polyploidy, hybridization, breeding systems, and introgression are carefully considered. Appendices cover botanical nomenclature as well as field and herbarium methodology. The text is copiously illustrated, using in large part the informative analytical drawings developed as part of the Generic Flora of the Southeastern United States project.
Although they are relative latecomers on the evolutionary scene, having emerged only 135?170 million years ago, angiosperms—or flowering plants—are the most diverse and species-rich group of seed-producing land plants, comprising more than 15,000 genera and over 350,000 species. Not only are they a model group for studying the patterns and processes of evolutionary diversification, they also play major roles in our economy, diet, and courtship rituals, producing our fruits, legumes, and grains, not to mention the flowers in our Valentine’s bouquets. They are also crucial ecologically, dominating most terrestrial and some aquatic landscapes. This fully revised edition of Phylogeny and E...
An indispensable, fully updated guide for everyone interested in identifying, studying, or conserving the flora of New England This comprehensive manual offers accurate, up-to-date, and clear information for identifying New England's remarkable array of tracheophytes (vascular plants, excluding mosses). With fully researched entries on some 3,500 native and nonnative species, the book is the first in decades to provide a complete and correct botanical reference for the region's noncultivated plants. The volume includes many new species not documented in New England before, while also excluding many species that have erroneously appeared in earlier manuals. Focusing on the taxonomy and distri...
Understanding the flowering plants of any region begins with the recognition of families. This remarkable volume, created to serve students, professionals, and other plant enthusiasts, covers 130 temperate to tropical families common in North America with detailed illustrations and modern referenced commentaries. Each family discussion includes a diagnosis and summary of characteristics, distribution data, important economic members, and pollination ecology. The book's most striking feature is Zomlefer's 158 original pen-and-ink plates depicting intricate dissections of 312 species. The content of the family discussions is geared to readers who have completed one introductory biology course. For readers less familiar with botanical terminology, Zomlefer provides an illustrated glossary of 551 terms with more than 300 drawings. Other important tutorial features are twenty-two detailed charts that compare pertinent characteristics of certain related plant groups and a general chart that summarizes the salient features of the families covered in the text. Both amateurs and professionals will particularly enjoy the chapter on examining, dissecting, and sketching live material.
This book is an invaluable compilation of ecological information on 244 species of trees, shrubs, and woody vines found in the northern half of the Florida peninsula and in the Florida Panhandle. It covers the full range of native species in the region as well as common exotic plants, drawing on original experience and field research by ecologist Robert Simons. For each species, Simons describes the plant’s leaves, flowers, and fruit, geographical distribution, size, and lifespan. He also discusses its typical habitats, soil and light requirements, water needs and flooding tolerance, adaptation to fire, economic importance, and the plants, insects, and diseases most often associated with i...
Beautifully illustrated with dozens of original full-color and black-and-white drawings, The Plants of Middle-earth connects readers visually to the world of Middle-earth, its cultures and characters and the scenes of their adventures. Tolkien's use of flowers, herbs, trees, and other flora creates verisimilitude in Middle-earth, with the flora serving important narrative functions. This botanical tour through Middle-earth increases appreciation of Tolkien's contribution as preserver and transmitter of English cultural expression, provides a refreshing and enlivening perspective for approaching and experiencing Tolkien's text, and allows readers to observe his artistry as sub-creator and his...
