Oxalidaceae, Christine H. S. Kabuye  (East African Herbarium). Flora of Tropical East Africa. 1971

Morphology General Habit

Perennial herb, with usually thin stems arising from a thick tuberous main rootstock 5 mm. or more across.

Morphology Stem

Stems erect or ascending, not rooting at the nodes, somewhat angular, loosely pubescent with spreading hairs, more densely so at the nodes and on young parts.

Morphology Leaves

Leaves alternate or rarely fasciculate, very like those of O. corniculata but with no stipules at the base of the petiole; leaflets very variable in size, usually softly hairy on both sides, sparsely so on the upper side, ciliate at margins.

Morphology Reproductive morphology Inflorescences

Peduncles axillary, usually l–l.5(–2.5) times as long as the subtending petioles; bracts 2–many, variable, linear to oblanceolate, ciliate; pedicels 1–2 cm. long, with short spreading hairs which sometimes appear curly on dry specimens.

Morphology Reproductive morphology Flowers Calyx

Sepals linear-lanceolate, up to 5 mm. long, often tinged with purple, softly hairy and ciliate at apex.

Morphology Reproductive morphology Flowers Corolla

Petals usually appearing pinkish in bud, sometimes with reddish markings in the throat and greenish-yellow at the base, 10 mm. long or rarely longer, glabrous, sometimes ciliate at the top.

Morphology Reproductive morphology Flowers Androecium Stamens Filaments

Short filaments glabrous or rarely hairy; long filaments glabrous or pilose, as long as the sepals or longer.

Morphology Reproductive morphology Flowers Gynoecium Pistil

Morphology Reproductive morphology Fruits

Capsule cylindrical, gradually tapering to the persistent styles, 5-lobed, up to 3 cm. long, closely pubescent with hairs usually pointing backwards.

Morphology Reproductive morphology Seeds

Seeds many in each locule, brown, somewhat flattened and transversely ridged.
