Species

Angiosperms > Gentianales > Rubiaceae > Tarenna

Characteristics

Small tree or shrub, 2.75–10 m. tall; young branches glabrous or with adpressed hairs, older stems square, covered with buff to red-brown sometimes flaking bark.. Leaf-blades drying black or greenish to brown, oblanceolate to obovate or sometimes broadly elliptic, 5–20 cm. long, 2–8.8 cm. wide, acuminate or sometimes acute at apex, cuneate at base, sometimes with margins undulate, chartaceous to subcoriaceous, shiny above, glabrous above or sometimes becoming pubescent towards base of midrib, glabrous to glabrescent with the nerves glabrous or glabrescent to pubescent beneath; domatia present; petiole 0.5–3 cm. long, glabrous or with adpressed hairs; stipule-limbs with a blackened area when dry, deltoid, 2–6 mm. long, gradually narrowed or with a subulate acumen 1–6 mm. long, glabrous or less often with adpressed hairs outside, eventually deciduous.. Inflorescences terminal on main and moderately short lateral branches, moderately lax to congested, sessile, usually with 1–3 pairs of pedunculate inflorescences arising from the next 1–2 nodes down, frequently with the supporting leaves reduced or absent, rarely with only the axillary branches present; primary inflorescence-branches 0.6–2 cm. long, covered with greyish to ± golden adpressed hairs; pedicels 0–8 mm. long, densely covered with adpressed hairs; bracteoles inconspicuous, subulate to filiform.. Calyx sparsely to densely pubescent; tube 1–1.5 mm. long; limb wider than tube, 1–2.25 mm. long, divided for ± half its length into ovate to deltoid or oblong lobes, apiculate.. Corolla white; tube 3–6.5 mm. long, glabrous outside, pubescent at throat; lobes oblong, 3.5–6 mm. long, 1.5–2.5 mm. wide, rounded, sometimes apiculate or tending to be emarginate.. Placenta narrowly obovate to rotund, moderately fleshy to fleshy bearing 2–11, impressed ovules. Fruit glaucous green (or white or ? pale blue) turning black (when dry), 4–8 mm. in diameter, 2-locular, containing 2–15 seeds; calyx-limb persistent.. Seeds brown, shiny, 2.5–4 mm. across, smooth.
