Turneraceae, R. Fernandes. Flora Zambesiaca 4. 1978

Morphology General Habit
An annual herb covered all over with long, appressed or subappressed yellowish hairs denser on young parts especially on petioles and nerves of the leaves.
Morphology Stem
Stem up to 27 cm. tall, erect, usually much-branched from the base, rarely simple; lower branches frequently as long as or longer than the main stem and decumbent or patent, the others patent or ascending, few-branched or unbranched, all terete, brownish to dark purplish.
Morphology Leaves
Leaves 1·5–4 × 0·5–1·2 cm., elliptic to elliptic-oblanceolate, attenuate-acute to subacute at the apex, cuneate at the base, entire in the proximal 1/3–1/2, serrate distally, very scattered along the stem and branches but very closely arranged and forming subcapitate aggregates at their extremities; lateral nerves ascending, somewhat prominent above like the midrib; petiole 1–5 mm. long.
Morphology Reproductive morphology Inflorescences Peduncles
Peduncle 1–2 mm. long and straight in flower, up to 5(6) mm. long and suddenly deflexed at the top in fruit, densely long-setose (the setae ascending) mainly towards the apex.
Morphology Reproductive morphology Inflorescences Bracteoles
Bracteoles 2, below the flower, very small, opposite.
Morphology Reproductive morphology Flowers
Flowers narrowly cylindrical, concealed by the subtending leaves; calyx 2–2·5 mm. long; lobes oblong, rounded at the apex and with 1–3 subapical setae.
Morphology Reproductive morphology Flowers Corolla
Petals 4–6 mm. long, narrowly oblanceolate-spathulate, obtuse, pale yellow to orange, glabrous, falling off with the calyx and the stamens after pollination.
Morphology Reproductive morphology Flowers Androecium Stamens
Stamens with somewhat unequal filaments and short, cordate, pale yellow anthers.
Morphology Reproductive morphology Flowers Gynoecium Pistil
Ovary narrowly ovoid, subglabrous; styles of unequal length (shorter in the brevistylous flowers, longer in the longistylous ones).
Morphology Reproductive morphology Fruits
Capsule 2–2·5 × 1·5 mm., ellipsoid-cylindrical to subglobose, smooth, papillose at the apex, reflexed, with 3–10 seeds.
Morphology Reproductive morphology Seeds
Seeds 1–1·5 × 0·7 mm., slightly curved, at first pale, then dark brown, later nearly black; aril cordate, thin, subhyaline, c. half as long as the seed.
