Book Description
This volume covers the orders Apiales (Asterids I) and Gentianales (except Rubiaceae; Asterids II). It is the last of five volumes to (almost) complete the treatment of the Asterids in this series after publication of Vols. VI (Cornales, Ericales, 2004), VII (Lamiales, 2004), VIII (Asterales, 2007) and XIV (Aquifoliales, Boraginales, Bruniales, Dipsacales, Escalloniales, Garryales, Paracryphiales, Solanales, Icacinaceae, Metteniusaceae, Vahliaceae, 2016). The present volume provides descriptions for 11 families with altogether 1021 genera. Identification keys are provided for families within orders and for all genera within families, and likely phylogenetic relationships are discussed. The wealth of information contained in this volume makes it an indispensable source for all working in pure and applied plant sciences.

Book Description
The succulent and Nama-karoo form part of the arid south-western zone of Africa, a vast region of rugged landscapes and low treeless vegetation. Studies of this unique biome have yielded fascinating insights into the ecology of its flora and fauna. This book, originally published in 1999, is the first to synthesise these studies, presenting information on biogeographic patterns and life processes, form and function of animals and plants, foraging ecology, landscape-level dynamics and anthropogenic influences. Detailed analyses of the factors distinguishing the biota of the Karoo from that of other temperate deserts are given and generalisations about semi-arid ecosystems challenged. The ideas expounded, the ecological principles reviewed, and the results presented are relevant to all those working in the extensive arid and semi-arid regions of the world.

Book Description
Found in a variety of forms, cacti and other succulents have elicited widespread interest and tremendous popularity worldwide. Although the subject of a certain amount of debate, about 10,000 species are recognized as belonging to the succulent group. Of these, an estimated 2,000 are threatened with global extinction in the wild and many more are regionally or nationally threatened mainly due to habitat destruction and collection for international trade.This Action Plan brings together from around the world current information on population status, threats and conservation of this particularly important group of plants. Prepared with conservationists, scientists, governments, protected area managers and grant-awarding bodies in mind, it suggests priorities for action and encourages collaboration among interested parties at all levels.

Book Description
The Illustrated Handbook of Succulent Plants represents the first comprehensive taxonomic treatment of succulents in thirty years. It covers over 9000 taxa of all succulents except Cactaceae. The Crassulaceae (stonecrop family) volume presents the first complete treatment of the family for many decades. The family is a very diverse group, and plants range from tiny insignificant annual herbs to perennial shrubs and trees. Many of the species have attractive flowers. The entire family consists of 33 genera and 23 hybrid genera with a total of 1410 species and 305 infraspecific taxa. The largest genus is Sedum (stonecrop, wallpepper) with 428 species. Other large genera are Aeonium (36), Crassula (195), Dudleya (47), Echeveria (139), Kalanchoe (144), Rhodiola (58), Sempervivum (63), and Tylecodon (46). A key to all genera is included. The descriptions of all accepted taxa are supplemented with typification and distribution data, full synonymy, literature references and 341 colour photos.

Book Description
"Includes more than 1,200 photographs of species and varieties from 195 different genera, and therefore it constitutes a unique work of reference for succulent enthusiasts and collectors." --Cover.

Book Description
Palynology is important in basic as well as in manifold applied sciences, as e.g. biology, medicine, forensics, earth history, climatology and food production. This volume is the first fully illustrated handbook of palynological principles and glossary terms, exclusively using LM and EM micrographs of superior quality. A comprehensive General Chapter on pollen morphology, anatomy, pollen development etc. based on the present knowledge in palynology introduces the reader in the world of pollen. The glossary part comprises more than 300 widely used terms illustrated with over 1.000 high quality light and/or electron microscopic pictures to show the character range of a term. Terms are grouped by feature, e.g. ornamentation, where each term is illustrated on a separate page, definition and original citation included and where necessary, provided with a comprehensive explanatory comment. The term's use in LM, SEM or TEM and its assignment to anatomical, morphological and/or functional pollen features is indicated by icons and colour coding, respectively. This handbook is not only a valuable source for students and researchers but also for all persons interested in pollen and its aesthetic beauty.

Book Description
Inselbergs are isolated rock outcrops that stand out abruptly from surrounding plains. Despite the widespread occurrence of granite inselbergs throughout all climatic and vegetational zones, their remarkably rich plant life was largely neglected in the recent literature. This richly and partly in color illustrated volume provides a detailed survey of all major abiotic and biotic features characteristic for inselbergs. The extreme environmental conditions on inselbergs are described in depth as well as specific adaptive traits of rock outcrop plants including their morphological, anatomical and physiological responses. The diversity and structure of inselberg plant communities are examined on a global scale with detailed regional accounts for different tropical and temperate zones.
