Arisaema is a large genus within the Arum family, consisting of about 200 species, subspecies, and varieties distributed widely around the globe. They are remarkable for their exotic-looking inflorescences-which inspired the common name of cobra lily-and for the fact that they can change sex from year to year. The Genus Arisaema (2002) was the first comprehensive study of the genus since 1920, and indeed the first ever in the English language. This second revised and updated edition includes more than 10 new species described since 2002, along with recent developments in taxonomy, geographical distribution of species, revised tables for keying species, and many new photographs.Coverage for each species (arranged by section) includes detailed descriptions of the subterranean stem, shoot, leaf, inflorescence, and fruiting spike, with notes on the flowering period, distribution, and habitat. Fabulous color photographs, many of plants in their natural habitat, are supplemented by color illustrations that clearly identify species. There are chapters on arisaemas in the wild and in cultivation, and on propagation, and cultivation notes are provided for each section.This new edition is the only comprehensive, up-to-date book on the genus Arisaema, and will be welcomed by botanists, plant collectors, arisaema aficionados, and gardeners.
