Descriptions

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

Morphology General Habit
Erect or sometimes probably scrambling shrubs or subshrubs
Morphology Leaves
Leaves opposite (or lower leaves rarely in whorls of 3 in P. capsulifera), petiolate; stipules with 1–2 subulate lobes
Morphology Reproductive morphology 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
Morphology Reproductive morphology Flowers Calyx
Calyx-tube elongate, ± oblong; lobes 5, ± subulate
Morphology Reproductive morphology Flowers 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
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens always included in the swollen part of the tube
Morphology Reproductive morphology Flowers Gynoecium 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
Morphology Reproductive morphology Flowers Gynoecium Ovary
Ovary 2-locular, each locule with many ovules borne on the marginal portions of very narrowly oblong curved placentas which resemble lamellae
Morphology Reproductive morphology Fruits
Fruit dry, mostly capsular, with rather incomplete loculicidal dehiscence or sometimes not dehiscent
Morphology Reproductive morphology Seeds
Seeds small, reticulate.

Morphology Reproductive morphology 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).
Morphology Reproductive morphology Flowers Calyx
Calyx tube elongate, ± oblong; limb-tube ± absent; lobes 5, subulate.
Morphology Reproductive morphology Flowers 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.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens always included within the swollen part of the corolla tube.
Morphology Reproductive morphology Flowers Gynoecium 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.
Morphology Reproductive morphology Fruits
Fruit dry, mostly capsular with rather incomplete loculicidal dehiscence or sometimes not dehiscent.
Morphology Reproductive morphology Seeds
Seeds small, reticulate.
