Heinsenia K.Schum.

Trees or shrubs with branching similar to that of many Rothmannia species and characteristic evergreen foliage. Leaves opposite, petiolate, thinly coriaceous, usually with ± transversely parallel venation; domatia absent or present and pubescent; stipules triangular, acute or acuminate, soon falling. Inflorescences 1–several or occasionally ± many-flowered on very short terminal branchlets subtended by a single leaf but often lateral and pseudoaxillary owing to the sympodial growth of the stem; bracts small. Calyx-tube ovoid to tubular; limb shortly cylindrical, with 5 triangular to lanceolate teeth. Corolla ± pubescent to densely adpressed silky outside, narrowly campanulate; corolla-lobes 5, ovate to lanceolate. Anthers linear, elongate, apiculate, sessile, usually medifixed, included or slightly to completely exserted; pollen grains simple. Ovary 2-locular; each locule with a pendulous placenta carrying 2–10 embedded ovules; style filiform or elongate-clavate, glabrous or rarely pubescent, apical part sometimes 10-ribbed, and divisible into lobes up to 4–5 mm. long bearing the stigmatic surfaces; the whole style is divisible almost to the base if pulled gently. Fruit fleshy, 1–several-seeded, subglobose, crowned by the persistent calyx-limb. Seeds subglobose with abundant endosperm, apparently devoid of a testa; embryo with radicle superior.
