Flora of the Azores.

New enlarged edition of this useful guide, which provides short descriptions for 650 of the about 1200 species of vascular plants found in the islands, including 400 full colour photographs. Not only the most prevalent species but also rare and unusual plants of startling beauty are illustrated and described, some of them for the first time. There is a lot of emphasis given to endemic species and plant invaders that constitute a serious threat to natural ecosystems of the Azores. The useful glossary in English, Portuguese and German introduces the lay readers to the scientific terminology.
