    [FTEA]

    Sterculiaceae, Martin Cheek & Laurence Dorr; Nesogordonia, Laurence Dorr, Lisa Barnett. Flora of Tropical East Africa. 2007

    Habit
    Deciduous shrubs or trees, often with swollen trunks
    Leaves
    Leaves entire or slightly 3lobed; palmately nerved from the base; domatia present or not; petiolate; stipulate
    Inflorescences
    Inflorescences axillary or subterminal, flowering either when leafless (FTEA) or when ± leafy
    Flowers
    Flowers bisexual or functionally unisexual with vestigial anthers
    Calyx
    Calyx gamosepalous, elongate-campanulate or fusiform-clavate, 4–5-lobed, the lobes short or long, often reflexed, sometimes persistent in fruit
    Corolla
    Petals 0
    Stamens
    Stamens fused in a globose head borne on a slender androgynophore; anthers 10–20, linear, sessile or subsessile, di-thecal, surrounding the carpels or pistillode
    Ovary
    Ovary of 5 coherent carpels (becoming free in fruit); 1–2 ovules per carpel; styles coherent, sometimes very short; stigma lobes 5, reflexed
    Fruits
    Fruiting carpels usually 5, stipitate, winged, somewhat inflated, membranaceous, dry, indehiscent, the seed(s) basal
    Seeds
    Seeds 1(–2), glabrous or pubescent; albuminous; radicle next to hilum.
    Note
    The African and Malagasy species appear to form a natural group. All have long, tubular or infundibuliform calyces with relatively short calyx lobes, and they are leafless when in flower. Molecular data (Wilkie et al. in Syst. Bot. 31: 160 (2006)) fail to support the current generic circumscription of Hildegardia; limited molecular sampling supports our argument based on floral morphology that the African and Malagasy species of Hildegardia form a natural group.
