Here, we present the first illustrated field guide to all woody plants from the Amazon. The work is divided over nine volumes. Volume I focuses on the fruits of woody plants known from the Guayanan Shield. It offers 208 plates with line drawings and aquarelle paintings of 2,000 species of fruit. Volumes II - IX describe and depict botanical and ecological field characters of all woody plants known from the Amazon. They cover 109 families, 1,000 genera and ±5,000 species, each volume treating families in alphabetical order. This volume (V) treats Leguminosae. This 'Flora Amazonica' is the result of my lifetime research on plant-animal relations in the Amazon. It is built upon 3 earlier works: 'Het Surinaams Vruchtenboek' (1977); 'Fruits of the Guianan Flora' (1985); and 'Wild Fruits from the Amazon' (2014-18). From 1986 on, I have worked on my magnum opus, along with other Amazon biodiversity projects. I now thank all botanists and field explorers, past and present, that collectedand named the myriad of plants I had to examine in order to compile it.
