Small shrubs 30–80 cm tall, with many stems, bark smooth or rarely rough and brownish; young branches sparsely tomentose with brownish, slightly twisted hairs to 0.4(–0.8) mm long, glabrescent when mature; buds densely tomentose. Leaves petiolate, petiole 2–4 mm long, 1.0– 1.4 mm in diam, tomentose; leaf blade lanceolate, elliptic or oblanceolate, or rarely obovate, 4–8 cm long, 1.5–3.5 cm wide, base symmetric or ±asymmetric, narrowly acute, apex acute or obtuse, ± apiculate, or rarely rounded, thinly coriaceous, green or greenish-brown and lustrous adaxially, yellowish-brown or yellowish-green and matte abaxially, tomentose when young, thinly tomentose or glabrescent when mature; main longitudinal veins 5–7, lateral main veins merged with midrib at 0.8–1.2 cm above blade base before separated, two outer lateral veins starting from or a little above base, outermost two main veins (if 7 mains veins present) very fine, most often disappearing at upper portion of blade margins, distinctly prominent on both surfaces; transverse veins sub-parallel or irregular, at angles of 55°–85° with midrib; veinlets reticulate, prominent on both sides. Inflorescence a supra-axillary spike; rachis to 19 cm long, tomentose with yellowish-brown hairs 0.1–0.4 mm long, remotely with flowers; bracts narrowly lanceolate, 1.5–5.0 mm long or rarely longer,

Fruit a drupe, ellipsoid, to 3.5 cm long, 1.5 cm in diam., attenuate toward both ends, reddish, apex with persistent floral parts.

Flowering and fruiting: —June–October.

Habitat and distribution: —Scrublands; 700–1000 m. Angola ( Cabinda, Lunda Norte), Democratic Republic of the Congo (Kinshasa) ( Figure 109 ).

Local usage: —Fruits edible.

Taxonomic notes: —With limited materials with both flowers and fruits, it is difficult to distinguish this species with Anisophyllea poggei , and/or even with A. dichostila . The diagnostic characters in the key use the size and shape of styles are temporary, and further investigations are needed to verify the identity of this species.
