This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this dissertation is to study the systematics and evolution of Euphorbiaceae vines (tribe Plukenetieae), a diverse pantropical lineage (~365 species and 18 genera) composed of three morphologically distinct subtribes, Dalechampiinae, Plukenetiinae, and Tragiinae. Through the course of my research I largely resolved the evolutionary history of Plukenetieae and made broader contributions to the study of pollen and seed evolution, pantropical biogeography, and plant diversification. In chapter two I developed the first well-sampled molecular phylogeny for Plukenetieae (154 terminals, ~93 species, 2,207 character dataset composed of ITS and psbA-trnH with indel gap-scored data), and determined baseline species group relationships of the tribe. Molecular phylogeny largely agreed with pollen morphology hypotheses and confirmed that the large genus Tragia was para- and/or polyphyletic and should be split into smaller genera. Analysis of pollen morphology revealed a trend towards aperture reduction and loss in Tragiinae, with four origins of weakly defined apertures and up to three origins of inaperturate pollen. In chapter three, I studied the seed size evolution of Plukenetia, a pantropical genus with large edible oil-rich seeds, by developing a near-exhaustive phylogeny (83 terminals, 20 of ~24 species, 5,069 bp dataset of ETS, ITS, KEA1 introns 11 and 17, TEB exon 17, matK, ndhF) and conducting ancestral state estimation and phylogenetic regression. Seed size evolution in Plukenetia was dynamic and associated with competing selective pressures of plant size, fruit type (and inferred dispersal syndrome), and seedling ecology. In chapter four I presented a revised sectional classification of Plukenetia based on phylogeny and morphological evidence, including three new taxa from South America. Chapters three and five included biogeographical investigations on Plukenetia and Plukenetieae. Analyses revealed that pantropical disjunct distributions arose one to three times in each subtribe via periodic long-distance dispersals from the Oligocene to the Pliocene, most often from South America to Africa and then Southeast Asia. Lastly, in chapter five, I developed an improved phylogeny for Plukenetieae (289 terminals, ~109 species, 5,160 bp dataset of ETS, ITS, KEA1 intron 11, TEB exon 17, matK, ndhF) to study the influence of innovative traits (twining growth form, stinging hair defences, and pseudanthial inflorescences) on diversification in the tribe. However, increased diversification was not associated with innovative traits. Instead, diversification was associated with clades that shifted into drier open habitats, aided by habitat expansion following the Late Miocene cooling period.

Available in PDF, EPUB and Kindle. Book excerpt: Modern angiosperm taxonomy or systematics provides a strong foundation for the progress of biological sciences as it incorporates studies on biosystematics, chemical and serological evidences, numerical taxonomy, cytogenetical and ecological evidences and many others. This book accounts for information on classical and fundamental aspects of taxonomy as well as its recent developments. Special attention has been paid to the chapters on origin of Angiosperms, Theory of Evolution and Evolutionary trends in Angiosperm Flowers. The International Code of Botanical Nomenclature, Important herbaria, Techniques for the preparation, storage and study of herbarium specimens, Botanical gardens, and Taxonomic literature are discussed in detail and includes the study of some selected families belonging to 21 orders. For each family, general features and evidence from anatomical, embryological, chromosome numbers and phytochemical data have been added and evolutionary trends discussed. Attention has also been drawn to economic importance and geographical distribution of these families. Illustrations for some members of these families have also been added.

Download or read book Flowering Plants. Eudicots written by Klaus Kubitzki and published by Springer Science & Business Media. This book was released on 2013-11-27 with total page 333 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents systematic treatments for the families and genera of the Malpighiales, which more recently have been recognised as a new major group of the eudicots. Apart from several herbaceous lineages (already treated in Vol. IX of this series), the order consists mainly of rainforest trees, particularly those of the understorey. Accompanied by other early eudicot lineages, this reflects the well-documented origin of the group as invaders into the conifer-, cycad- and seed fern-dominated forests of the Cretaceous which, at that time, were transformed into the tropical rainforest biome. In this volume, 24 families with 429 genera comprising over 12,000 species are treated. Many of these belong to the vast family of the Euphorbiaceae (here conceived in a broader sense), followed by the Violaceae, whereas some of the remaining families are very small and even relictual. The revised classification includes a complete inventory of the genera belonging to the families treated in this volume, along with their diagnostic features and keys for their identification. References to the latest taxonomic literature and links to many different disciplines important to modern plant systematics make the volume a valuable source of information on the manifold aspects of plant diversity.

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.
