This second edition, fully revised and updated, takes into account latest results in phylogeny of Arisaema, and incorporates all new species described since 2002, the year of publication of the first edition. It provides information on plant names, synonyms, botanical types, geographic distributions and habitats, together with notes on cultivation. One obvious change from the first edition is the artwork, the goal being to make descriptions readily comprehensible; new and improved images make the book visually attrative. This volume is easy to use, with comparative drawings of leaves and inflorescences as well as comprehensive identification tables.
