An Annotated Checklist of the Vascular Flora of Guinea-Bissau (West Africa)

A Checklist of Guinea-Bissau’s vascular flora is presented, based on the inventory of herbarium material and on recent collections. In addition to the name, we cite for each taxon the basionym and synonyms, the life form and habitat, as well as the chorology, Raunkiaer’s biological type, phenology and vernacular names if known. 1507 specific and infra-specific taxa were recorded, of which 1459 are autochthonous, belonging to 696 genera. This shows a higher diversity than the 1000 species estimated so far. In the autochthonous flora there are 22 species of Pteridophyta from 14 families; 1041 taxa of Dicotyledons from 107 families, and 396 taxa of Monocotyledons belonging to 33 families. Three taxa are probably endemic to the country.
