    Rafflesiaceae, B.L. Stannard. Flora Zambesiaca 9:2. 1997

    Habit
    Small parasites of trees in the family Leguminosae, vegetatively much reduced, only the flowers emerging on the smaller branches of the host.
    Flowers
    Flowers numerous, involucrate, globose, ovoid or ellipsoid, unisexual by abortion. Male flowers: stamen filaments connate into a tube about a central column (pistillode); pistillode (and gynandroecial column) expanded apically into a disk (pileus) fringed with papillae; anthers sessile, 1–several-seriate below the pileus rim. Female flowers: ovary inferior surmounted by a fleshy disk; disk flat, concave or convex, sometimes appearing as a simple extension of the style; style short, thick, conical or cylindrical; stigma capitate, the stigmatic surface hemispherical or a subapical annular ring.
    Perianth
    Perianth segments 4–12, free, similar to the bracts, imbricate, persistent, enclosing an annular disk at the base.
    Fruits
    Berry globose, surrounded by persistent bracts and perianth segments.
