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.
In this book, Walter Judd and Grant Judd give detailed species accounts of every plant found in Tolkien's universe, complete with the etymology of the plant's name, a discussion of its significance within Tolkien's work, a description of the plant's distribution and ecology, and an original hand-drawn illustration in the style of a woodcut print.
This book presents a synthesis of critical new information for the Melastomataceae, one of the ten richest families among flowering plants with over 5,800 species that has its diversity highly concentrated in tropical or subtropical areas. It describes the family’s global diversity and distribution and summarizes recent advances in systematics, evolution, biogeography, reproductive biology and ecology.
Sehnsucht: The C. S. Lewis Journal, established by the Arizona C. S. Lewis Society in 2007, is the only peer-reviewed journal devoted to the study of C. S. Lewis and his writings published anywhere in the world. It exists to promote literary, theological, historical, biographical, philosophical, bibliographical and cultural interest (broadly defined) in Lewis and his writings. The journal includes articles, review essays, book reviews, film reviews and play reviews, bibliographical material, poetry, interviews, editorials, and announcements of Lewis-related conferences, events and publications. Its readership is aimed at academic scholars from a wide variety of disciplines, as well as learned non-scholars and Lewis enthusiasts. At this time, Sehnsucht is published once a year.

The treatise presents a wide range of information on different facets of world food crops. It justifies the present state of knowledge with reference to crop history, initial and latest developments with evolutionary approach based on karyotaxonomic and geographical evidence. The author has endeavored to dilate attempts for crop domestication and cultivation by worldwide human societies. These are supported by various considerations like ethnology, philology, ancient and religious treatises, archaeological evidence, works of pioneers, various human affairs, etc. He further based his writing on botanical conclusions accrued from distribution, number of varieties, occurrence of wild types, agr...
