Located in the southeastern half of Venezuela, the Venezuelan Guayana is the core area of what has been called "The Lost World." It is home to nearly 10,000 species of vascular plants, including many endemic species and genera. The Flora of the Venezuelan Guayana is the first full scientific account of the plants of the region. This volume is the first of the alphabetical sequence of family treatments, beginning with ferns and fern allies. Includes keys, descriptions, and illustrations of more than half the species treated.

With one volume each year, this series keeps scientists and advanced students informed of the latest developments and results in all areas of the plant sciences. The present volume includes reviews on genetics, cell biology, physiology, comparative morphology, systematics, ecology and vegetation science.

" . . . includes the countries of Guyana and Surinam, French Guiana (a part of France) and the Venezuelan states of Amazonas, Bolivar, and Delta Amacuro. The checklist contains 257 vascular plant families with 13,367 species." -- from abstract p. [2].
