    Note
    Raphionacme brownii is a pyrophyte and can be found flowering two weeks after a fire. R. brownii is known from just north of the Uganda/South Sudan border, its absence from the FTEA area is probably due to poor collecting. A U.K.W.F. ed. 2: 175 (1994) record from K 4, Langata, has not been substantiated.
    Distribution
    Range: Senegal, Sierra Leone, Guinea, Guinea Bissau, Mali, Burkina Faso, Ivory Coast, Ghana, Togo, Benin, Nigeria, Chad, Central African Republic and South Sudan Flora districts: U 1?
