Scandent shrub or liana with stems over 6 m long. Leaves opposite, simple and entire; stipules 4–10 mm long, usually falling off; petiole 3–12 mm long; blade obovate, 7–24 cm × 4–10 cm, base cuneate to truncate, apex acuminate, pubescent below, pinnately veined with lateral veins in 8–15 pairs. Flowers solitary, terminal on lateral branches, bisexual, regular, 5-merous, very fragrant; pedicel up to 1 cm long; calyx tubular, 2–4 cm long, widening at apex with ovate-lanceolate lobes up to 2.5 cm × 1.5 cm, densely pubescent; corolla tubular, tube 10–16 cm long, lobes ovate to lanceolate, 4–8 cm × 2–4.5 cm, white, yellowish or greenish with red-purple streaks inside, pubescent; stamens inserted in the upper part of the corolla tube, sessile, anthers up to 3 cm × 3 mm; ovary inferior, 1-celled, style with glabrous columnar basal part and pubescent ellipsoid upper part up to 3 cm × 1 cm, shortly 2-lobed at apex. Fruit a leathery, almost globose berry up to 8 cm × 6 cm, with 10–12 longitudinal grooves and more or less persistent calyx tube, many-seeded. Seeds discoid. Adenorandia comprises a single species and is classified in subfamily Rubioideae, tribe Gardenieae. It is closely related to the larger genera Gardenia and Rothmannia. In Gabon the fruits of another Rubiaceous climber, Aoranthe annulata (K.Schum.) Somers (synonym: Randia letestui Pellegr.), also produce a black dye, which is similarly used. |

Adenorandia kalbreyeri will remain of minor importance as source of a dye. Its phytochemistry in relation to its dyeing properties, as well as its ornamental potential deserve more attention. |
