Novitates Gabonenses 88: additions to the flora of Gabon and new records of little-known species

摘要

Background and aims - The intensive botanical prospections carried out in Gabon since the publication of the national checklist in 2006 have resulted in c. 34300 new specimens (amounting to 30% of all collections made in the country) and an annual increase of 25 species in average. As a result, 5175 species of vascular plants are now recorded from Gabon, of which 650 are considered endemic. However, most of the recent discoveries have not yet been published. This paper is the first of a series documenting additions to the flora of Gabon, and new records of poorly known species. It concerns specifically new records from the Lower Ogooue Ramsar site, the third largest delta of Africa, and certainly the most intact, which includes 80% of the country 's wetlands and a wide variety of other habitats.
