Phylogeny and Evolution of the Angiosperms

Pages : 587
Book Description
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.

Monograph of Mitrephora (Annonaceae)

Pages : 192
Book Description
"The genus Mitrephora (Annonaceae) comprises 47 species of small to medium-sized trees, growing in tropical lowland and submontane forests throughout Southeast Asia. The centers of diversity lie in Borneo, where there are 12 species, and the Philippines, where there are 11 species. The flowers are pendent and hermaphroditic, with two whorls of petals, of which the outer petals are larger. The inner petals are apically con-nivent over the productive structures, forming a partially enclosed pollination chamber with small apertures between the basal claws of the petals that enable entry by pollinators. A field study of the pollination ecology of M. heyneana in Sri Lanka (the first such study for the genus) revealed pollination by small nitidulid beetles, although it is possible that other species may be fly-pollinated. This monograph is the first comprehensive taxonomic revi-sion of the genus. The work is based on a comprehensive study of comparative morphology and anatomy, including a survey of previously published work. Conservation assessments are provided for each species, according to current IUCN Red List categories and criteria. All species are mapped and many are illustrated with line drawings and/or photographs. Separate keys for flowering and fruiting material are included, as well as regional keys. Seven new species (M. amdjahii, M. endertii, M. kostermansii, M. multifolia, M. sorsogonensis, M. sundaica, and M. uniflora) and one new combination (M. macrocarpa) are proposed"--Publisher's description.

Book Description
This synthesis of the growing body of information from research on epiphytes and their relations with other tropical biota provides a comprehensive overview of basic functions, life history, evolution, and the place of epiphytes in complex tropical communities. Epiphytes comprise more than one-third of the tropical vascular flora in some tropical forests. Growing within tropical forest canopies, epiphytes are subject to severe environmental constraints, and their diverse adaptations make them a rich resource for studies of water balance, nutrition, reproduction and evolution.
