Raphia sudanica is distributed from Senegal and Gambia eastwards to northern Nigeria. Plantations have been established in Nigeria. Raphia sudanica occurs in freshwater swamps and riverine forest in the savanna zone. It tolerates drier conditions than other Raphia spp. It is always gregarious and locally abundant, forming dense thickets. (PROTA)
