    Bark
    Bark smooth or rough, with or without lenticels
    Leaves
    Leaves alternate, rarely opposite, membranous or coriaceous Leaves alternate, rarely opposite, membranous or coriaceous.
    Flowers
    Flowers bisexual, very rarely unisexual, 4–5-merous, sessile or pedicelled in spicate inflorescences or ebracteate few-flowered fascicles or bracteolate few to many-flowered terminal or axillary heads, rarely compound Flowers bisexual, very rarely unisexual, 4–5-merous, sessile or pedicelled in spicate inflorescences or ebracteate few-flowered fascicles or bracteolate few to many-flowered terminal or axillary heads, rarely compound.
    Bracts
    Bracts present, usually persistent, sometimes leaf-like, rarely missing Bracts present, usually persistent, sometimes leaf-like, rarely missing.
    Calyx
    Calyx tube cylindric, glabrous or pubescent, usually articulated above ovary, upper and lower parts often with indumentum differences, the upper part falling off after flowering; lobes imbricate, always shorter than the tube, erect, spreading or reflexed, coloured Calyx tube cylindric, glabrous or pubescent, usually articulated above ovary, upper and lower parts often with indumentum differences, the upper part falling off after flowering; lobes imbricate, always shorter than the tube, erect, spreading or reflexed, coloured.
    Corolla
    Petals 4, 8 or 10, alternating with the calyx lobes, entire or more or less deeply divided, membranous or fleshy, often scaly or glandular, sometimes missing Petals 4, 8 or 10, alternating with the calyx lobes, entire or more or less deeply divided, membranous or fleshy, often scaly or glandular, sometimes missing.
    Stamens
    Stamens 4, 8 or 10 in 1 or 2 whorls, those of the upper opposite the calyx lobes, exserted or enclosed in the throat of the calyx tube, very rarely aborted; anthers sessile or with very short filaments, sometimes heteromorphic. Ovary sessile or shortly stipitate, 1-locular, glabrous or pubescent; disk membranous, cup-shaped or lobed, sometimes minute or lacking; style filiform, lateral; stigma capitate or club-shaped, papillate Stamens 4, 8 or 10 in 1 or 2 whorls, those of the upper opposite the calyx lobes, exserted or enclosed in the throat of the calyx tube, very rarely aborted; anthers sessile or with very short filaments, sometimes heteromorphic.
    Fruits
    Fruit dry, small, enclosed by the persistent base of the calyx tube Fruit dry, small, enclosed by the persistent base of the calyx tube.
    Note
    The number of calyx lobes and the presence or absence of petals (petaloid scales) are the only generic points of distinction between Gnidia, Lasiosiphon and Arthrosolen. One and the same individual can have both 4- and 5-merous flowers. The petals can be well developed or fully aborted within one and the same specimen. Considering the great variation in these characters and in agreement with the opinion of most recent authors Lasiosiphon and Arthrosolen have been treated as synonyms of Gnidia. See also discussion by Peterson in Bot. Not. 112: 465 (1959).
    Distribution
    The largest genus within the family with c. 140 species, the major part in tropical and southern Africa but extending to Arabia (1 species), southern India and Sri Lanka; also c. 20 species are endemic in Madagascar.
    Habit
    Perennial herbs, shrublets or shrubs, often ericoid, or trees. Perennial herbs, shrublets or shrubs, often ericoid, or trees
    Stem

    Pistil

    Seeds
    Seed with scanty or no endosperm. Seed with scanty or no endosperm.
