    Ecology
    Dense shade in intermediate forest; 1600–1700 m

    Note
    Two specimens seem to belong here, but lack the gemmae so key out to A. inaequilaterale: Uganda, U 2, Kigezi District: Bwindi National Park, Feb. 1995, Poulsen et al. 729! and Tanzania, T 3, Lushoto District: Shengena Forest Reserve, Gonja, Feb. 1988, Kisena 359! The correct name of this plant is uncertain. The position of the gemma in the centre of terminal pinna is constant and unique for EA.
