    Rubiaceae, B. Verdcourt. Flora of Tropical East Africa. 1976

    Habit
    Erect or sometimes probably scrambling shrubs or subshrubs
    Leaves
    Leaves opposite (or lower leaves rarely in whorls of 3 in P. capsulifera), petiolate; stipules with 1–2 subulate lobes
    Flowers
    Flowers fairly large, hermaphrodite, 5-merous, sessile, heterostylous, in several–many-flowered cymose terminal inflorescences; 1–several of the peripheral flowers have 1 of the calyx-lobes enlarged into a large coloured venose stipitate lamina
    Calyx
    Calyx-tube elongate, ± oblong; lobes 5, ± subulate
    Corolla
    Corolla-tube narrowly cylindrical, the upper part containing the anthers swollen; lobes (4–)5, ovate, induplicate-valvate, usually drawn out into a filiform appendage that is very evident in the buds which have 5 apical subulate projections; throat velvety hairy
    Stamens
    Stamens always included in the swollen part of the tube
    Pistil
    Style ± 3/4 the length of the corolla-tube in short-styled flowers; stigmas just exserted in long-styled flowers; stigma bilobed, the lobes thick, linear or ovoid
    Ovary
    Ovary 2-locular, each locule with many ovules borne on the marginal portions of very narrowly oblong curved placentas which resemble lamellae
    Fruits
    Fruit dry, mostly capsular, with rather incomplete loculicidal dehiscence or sometimes not dehiscent
    Seeds
    Seeds small, reticulate.

    Flowers
    Flowers fairly large, hermaphrodite, 5-merous, sessile, heterostylous, in several- to many-flowered cymose terminal inflorescences; 1–several of the peripheral flowers usually with one of the calyx lobes expanded into a large coloured venose stipitate lamina (calycophyll) (TAB. 73/A5) (not in the species described below).
    Calyx
    Calyx tube elongate, ± oblong; limb-tube ± absent; lobes 5, subulate.
    Corolla
    Corolla tube narrowly cylindrical, the upper part containing the anthers swollen; lobes (4)5, ovate, induplicate-valvate, usually drawn out into a filiform appendage which is very evident in the buds which have 5 apical subulate projections; throat velvety hairy.
    Stamens
    Stamens always included within the swollen part of the corolla tube.
    Pistil
    Ovary 2-locular, each locule with many ovules borne on the marginal portions of very narrowly oblong curved placentas which resemble lamellae; style about three quarters the length of the corolla tube in short-styled flowers, with stigmas just exserted in long-styled flowers; stigma bilobed, the lobes thick, linear or ovoid.
    Fruits
    Fruit dry, mostly capsular with rather incomplete loculicidal dehiscence or sometimes not dehiscent.
