XVI International Botanical Congess

The study led to the floristic inventory and the description of 40 species (of the 93 presently known in the R.D.C. flora) and 2 varieties, divided into 4 subgenera (Sycomorus Gasp., Sycidium Miq., Urostigma Gasp. and Bibracteata Mildbr. and Burret) within the genus Ficus in the urban area of Kisangani. The taxonomic description was concentrated on the characters of different organs. Dichotomous keys for determination separately on vegetative characters and reproductive characters have been established.
