Covering 7 genera and 223 species, this is the first modern full list of the important genus Magnolia (128 species). Current systematic research is discussed, plus there is information on life forms, distribution and conservation status. The extensive bibliography covers the most relevant taxonomic literature. This is an essential reference for botanists, nurserymen and enthusiasts.

Dioscoreales are a small but systematically and economically significant order of monocotyledons. The most diverse and important member is the yam genus, Dioscorea L., a source of dietary starch at macroeconomic to rural community levels. Other species of Dioscorea provided the chemical basis of corticosteroid drugs and oral contraceptives. Ally families comprise the unusual, largely achlorophyllous (heteromycotrophic) Burmanniaceae and the relatively unspecialised Nartheciaceae. The World Checklist of Dioscoreales lists all validly published names of yams and their allies, providing the source of their publication and indication of which names are currently accepted and which are synonyms, making it a standard nomenclatural reference for further research into this important family. The World Checklist of Dioscoreales: .Lists all names ever published .Lists all accepted species with their geographical distribution .Indicates full synonymy .Provides a single source guide to the correct names of all yams and their allies .Provides an invaluable reference for applied yam researchers, e.g. pathologists, geneticists, plant breeders, conservationists, foresters, ethnobotanists, ethnoarchaeologists and anthropologists

The sedge family, Cyperaceae, is the third largest family of monocotyledonous plants They are of significant economic importance, especially among rural communities in the tropics, where sedges are intensively used. The World Checklist of Cyperaceae is a unique resource that lists all validly published names of sedges, providing the source of their publication and indication of which names are currently accepted and which are synonyms. It will be a standard nomenclatural reference for further research into this important family. The World Checklist of Cyperaceae: .Lists all sedge names ever published .Lists all accepted species with their geographical distribution .Indicates full synonymy .Provides a single source guide to the correct names of all sedges .Is an invaluable reference for agriculturists, horticulturists, ecologists, conservationists and plant biologists.

Myrtaceae is the ninth largest flowering plant family; it is economically important in the production of timber, gums, essential oils, fruits and spices and contains many commonly cultivated ornamentals. This family is particularly rich in large genera, often found in some of the world's most threatened ecosystems where their fruits comprise an important part of the diet of primates and birds. The similarity of Myrtaceae species is high and its taxonomic and nomenclatural history is complex, resulting in notorious difficulties in basic identification, inventory compilation and floristic treatment. World Checklist of Myrtaceae is a much needed work that lists all validly published names in the family, providing the source of their publication and indicating which names are currently accepted and which are synonyms. This makes it the standard nomenclatural reference for further research into this important family.

This volume presents the first full list of names of the 54 genera and 1175 species that make up Sapotaceae. Sapotaceae (the argan, chicle or gutta-percha family) are found throughout most of the wetter tropics and subtropics, and are ofconsiderable direct economic importance as sources of fine timber, latex, fruit, vegetable oil and amenity trees.
