Descriptions

Rubiaceae, D.M.Bridson & B.Verdcourt. Flora Zambesiaca 5:3. 2003

Morphology General Habit
Bush or small tree, 1–3 m tall; young branches glabrous to pubescent; older branches covered with reddish-brown or grey bark.
Morphology Leaves
Leaf blades drying bronze or greyish-green, 4–11.2 × 1.5–5(6.5) cm, oblanceolate to oblong or less often obovate, obtuse, acute or shortly acuminate at the apex, cuneate at the base, glabrous to sparsely pubescent above, glabrous except for the nerves or pubescent beneath; lateral nerves in 8–10 main pairs; domatia absent or sometimes with a few axils with denser hairs; bacterial nodules small, dot- like, few, scattered; petioles short, 1.5–5 mm long; stipules 0.4–1.2 cm long, triangular with a stiff acumen, glabrous or pubescent outside.
Morphology Reproductive morphology Inflorescences
Inflorescences compact, (1.8)2–4 cm across (excluding corollas); primary inflorescence branches 1.5–2 mm long; secondary branches very reduced; pedicels 1–2 mm long, glabrous or pubescent; bracts c. 2 mm long, stipule-like. Inflorescence-supporting branches 3–10.5 cm long, slender, bearing 2–3 pairs of leaves clustered at the apex.
Morphology Reproductive morphology Flowers Calyx
Calyx tube 1–1.25 mm long, glabrous or densely pubescent; limb-tube 0.75–1 mm long; lobes 0.65–13 × 0.75–1.5 mm, linear- lanceolate, pubescent or ciliate.
Morphology Reproductive morphology Flowers Corolla
Corolla white (or ?lavender); tube only shortly exceeding the calyx lobes, 0.75–1.4 cm long, 1–1.25 mm wide at the top, glabrous outside, not bearded at the throat; lobes 4–6 × 1.5–2 mm, ± oblong, acuminate.
Morphology Reproductive morphology Fruits
Fruit pale green, 7 mm across, crowned by persistent calyx limb.
Morphology Reproductive morphology Seeds
Seed greyish, c. 4 mm wide, very finely rugulose on convex face.
