The Flora of Ecuador, comprises all vascular plants, including commonly cultivated and escaped species, of the Ecuadorean mainland. It describes families, genera and species, and provides keys to genera and species. Remarks on nomenclature, intraspecific variation, Ecuadorean distribution and total range are included. Synonyms and collections studied are listed. Illustrations are provided for many taxa and descriptions of a large number of new taxa are published for the first time. The Flora is published family by family (or in the largest families as parts thereof). The volumes are issued at irregular intervals as typescripts become ready for printing. The sequence and circumscription of the families follow, with minor deviations, Engler's Syllabus der Pflanzenfamilien, ed. 12. Treatments of many families are in preparation by specialists from different parts of the world, mainly Europe and the Americas. The account for the family describes ten genera and 98 species.
