Flora of the Guianas is an illustrated and systematic flora of French Guiana, Surinam, and Guyana. Each family is published in fascicles, which cover Phanerogams (Series A), Ferns and Fern Allies (Series B), Bryophytes (Series C), Algae (Series D), and Fungi and Lichens (Series E). It is an ongoing project, and various fascicles are already available. The Flora in general follows the format of other modern floras such as the Flora of Ecuador and Flora Neotropica. The treatment provides fundamental and applied information; it covers, when possible, wood anatomy, chemical analysis, economic uses, vernacular names, and data on endangered species.
