    Style
    Style with neck 2–3 mm long; stigma 0.7–0.8 mm across, capitate
    Ecology
    Mainly in dry mixed woodland and coastal bushland, occasionally in miombo and mopane, up to 1150 m, on a wide variety of hosts, commonly Acacia, Combretum, Sterculia, with an aberrant form on Uapaca extending the range further into Malawi, Zambia and Katanga (Shaba) Province of Dem. Rep. Congo and up to 1750 m; flowering in most months, but most commonly in the dry season.
    Note
    Differs significantly from T. oleifolius in the lack of any conspicuous indumentum, apart from glandular papillae on the petiole and often the bracts. The species rarely grow together though their total ranges overlap widely. T. forbesii may also be confused with T. dependens, but easily distinguished by the short calyx. The populations growing on Uapaca are quite widely distributed, and somewhat coherent in their short peduncles and generally broad leaves. This element may be independently derived from T. dependens, but is not clearly distinguishable on current information.
