Download or read book Euphorbia in Southern Africa written by Peter V. Bruyns and published by Springer Nature. This book was released on 2022-07-14 with total page 515 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a new account of Euphorbia in southern Africa. Euphorbia is the second largest genus of plants in the world. Southern Africa enjoys a high diversity in Euphorbia and 170 species occur here naturally. Of these 170 species, 128 or 74% are endemic. Where most species of Euphorbia in the northern hemisphere are herbs or shrubs, most of those in southern African are succulent. These succulents range from small, almost geophytic forms where the tuber is larger than the above-ground parts to huge trees 6 to 15 m or more in height. Many of them are spiny. There are also small numbers of herbaceous species in southern Africa and many of these are also dealt with here. The last account of the succulent species for southern Africa was published in 1941 and much new data has accumulated since then. Our understanding of the relationships of the species in Euphorbia has also been greatly enhanced by recent analyses of DNA-data, which led to new and unexpected results. From this new information an entirely new classification was developed, in which Euphorbiawas divided into four subgenera. This provides the taxonomic framework for the presentation of our species here. Around ten new species have been described and these are presented in detail for the first time. This monograph is made up of two volumes. Volume 1 contains an extensive introductory chapter with an overview of the genus in the region, emphasizing many of its important and distinctive features. This is followed by Chapter 2, which deals with subgenus Athymalus. Of the four subgenera, this one is by far the most diverse in southern Africa, with 80 species. Volume 2 contains Chapters 3 (subg. Chamaesyce, 34 species), 4 (subg. Esula, 11 species) and 5 (subg. Euphorbia, 45 species), as well as an additional Chapter 6 covering the remarkable diversity of subg. Euphorbia in Moçambique. Each of Chapters 2 to 5 includes a key to all the species, followed by an account of each of them. This account includes synonymy, a description, data on distribution and habitat, line-drawings of floral features and other diagnostic details, notes on how the species is distinguished from its closest relatives and a brief history of its discovery. Several colour photographs are included for each species, illustrating its habitat, vegetative habit and flowering features, demonstrating key points distinguishing it from others and often showing its variability. Euphorbia is an important component of the vegetation in many of the drier parts of southern Africa. This book is based on a thorough evaluation of the vast herbarium record for southern African members of Euphorbia, on the extensive field-work conducted in the region and the wide taxonomic experience of the author. It is believed that both the professional botanist and the layman will find much that is new and informative in this monograph.

Available in PDF, EPUB and Kindle. Book excerpt: This is the first complete and illustrated monograph of the genus Lachenalia, a horticulturally important and botanically diverse plant group. Lachenalia ranks with Gladiolus as one of the two most popular genera of South African bulbous plants worldwide, and next to Ornithogalum is the second-largest member of the family Hyacinthaceae in southern Africa.The flowers of some species have exceptionally showy blooms that occur in numerous interesting colours, shapes and sizes, and their fascinating leaves, many of which are attractively spotted or barred, or covered with attractive hairs or pustules. The flowers of many species are attractive in another dimension in that they emit distinctive aromas, ranging from spicy (like cloves) to various degrees of sweet (like a mixture of carnations and orchids), while one species is strongly coconut-scented.All species are described, classified and illustrated, with detailed text on history, morphology, phylogeny, phytogeography, pollination biology, cultivation and propagation. This book includes many highly attractive species which have never been illustrated in colour before, with 11 new taxa, ten of which are new species.This will become the standard reference work on all aspects of the genus and will appeal to botanists and taxonomists, bulb-growers, horticulturalists, gardeners, collectors of fine botanical works, ecologists and nature conservationists, as well as libraries and universities.

Download or read book Phylogeny and Evolution of the Angiosperms written by Douglas Soltis and published by University of Chicago Press. This book was released on 2018-01-24 with total page 587 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Evolution of the Angiosperms provides an up-to-date, comprehensive overview of the evolution of and relationships among these vital plants. Incorporating molecular phylogenetics with morphological, chemical, developmental, and paleobotanical data, as well as presenting a more detailed account of early angiosperm fossils and important fossil information for each evolutionary branch of the angiosperms, the new edition integrates fossil evidence into a robust phylogenetic framework. Featuring a wealth of new color images, this highly synthetic work further reevaluates long-held evolutionary hypotheses related to flowering plants and will be an essential reference for botanists, plant systematists, and evolutionary biologists alike.

Download or read book Identification Guide to Southern African Grasses written by Lyn Fish and published by . This book was released on 2015 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Grasses are very important features of the landscape and occur to a greater or lesser extent in all of the vegetation types of southern African. The importance of good grazing grasses for both wild and domesticated animals is well known. Some species are indicators of good or bad veld management and are useful to farmers and conservators. Crop farmers have to deal with undesirable grasses in their fields and the custodians of our indigenous vegetation need to correctly identify any alien invaders. This identification guide relies primarily on the use of keys and descriptive information to aid the user in identifying a grass species. It contains some of the best information needed to identify southern African grasses. Keys to grass genera and species are provided, and in some instances also keys to easily confused taxa. For each species, a combination of useful characters is provided, and where applicable, line drawings of the spikelet or parts thereof accompany the identification keys. Species descriptions and distribution maps are hugely important and add to the identification of grasses."--Back cover.
Download or read book Muthi Myths written by Heather Dugmore and published by . This book was released on 2008 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this book are fifty-two compelling tales that will lead the reader on a journey of discovery of the African continent. It tracks the ancient grail of traditional African medicine or muthi. The journey takes one year, with one story for each of the fifty-two weeks. Many of the stories inherited through Africa s compelling oral tradition are between these covers: committed to paper for the first time ever.The ancient African people were the first aromatherapists who well understood the effect of plants on the human body, mind and soul. Innately spiritual, the thousands of lineages of African people across thousands of years have all used plant medicines for healing, always with the blessing of their ancestors.Knowledge of African plant mythology and its associated healing practices is most certainly a grail because on this great continent we call Africa; knowledge has always been an oral tradition. Because it was never written down, thousands of years of healing wisdom and intelligence have been lost in the transference from one generation to the next.This book endeavors to bring to light the deep history of fifty-two of the thousands of indigenous medicinal plants of Africa before it is too late. The focus is towards Southern Africa because this region is a hotspot of cultural and botanical diversity. Unlike the healing knowledge of other ancient cultures, such as India or China, little of Africa s healing history is recorded.As you read the stories about fifty-two of the continent s prominent indigenous plant cures, the authors hope you, too, will experience some of the magnetism, mystery and wisdom of Africa. They hope it will help you understand a bit more about yourself and about our species: the human being."
