Information
Shrub or small tree 2.5–6 m tall; young branches square in section, sparsely puberulous to puberulous; bark pale grey.Leaf blades 1.3–3 × 0.9–2.1 cm, obovate, rounded at apex, acute to somewhat attenuate at base, coriaceous, shiny on upper surface, glabrous, margins recurved; lateral nerves in 2–3 main pairs but sometimes only 1 pair clearly apparent; tertiary nerves obscure; domatia pit-like, glabrous or sometimes absent; petioles 2(3) mm long, puberulous; stipules 1–2.5 mm long, truncate at their base with a linear decurrent lobe, puberulous outside.Flowers 4-merous, borne in 10–35-flowered pedunculate corymbs; peduncles 8–22 mm long, puberulous or sparsely pubescent; pedicels 1–4 mm long, glabrescent to sparsely pubescent; bracteoles inconspicuous.Calyx tube 1 mm long, glabrous to glabrescent; limb 0.25 mm long, repand or somewhat dentate.Corolla cream-coloured; tube 1.5–2.5 mm long, with a ring of deflexed hairs at the throat; lobes 2.5–3 × 1–1.25 mm, oblong, acute.Anthers reflexed.Style c. 6 mm long; pollen presenter 0.75–1.25 mm long; disk glabrous.Immature fruit 6.5 × 6 mm, ± oblong in lateral view.
Habitat
Principally with Afzelia quanzensis, Syzygium, Mimusops caffra and Dialium schlechteri
Altitude range
0–50 m.

Distribution
Mozambique M Marracuene to Maputo (Lourenço Marques), fr. i.iv.1983, Groenendijk & de Koning 292 (K; LMU).
Distribution (external)
South Africa (northern KwaZulu-Natal)
Notes
This species is very close to Psydrax obovata, differing in the smaller size of the leaves and flowers. More gatherings may indicate that varietal rank within Psydrax obovata would be more appropriate, or even that it cannot be kept separate at any level. However, as mature fruit have not yet been seen, the present status is maintained for the time being.
