Notes

Tree to 30 m and 50 cm Ø; bole cylindrical with a distinct taper; in rainforest and swampy areas, along rivers and in gallery forest. Bark light grey-brown, smooth, thin, flaking with a pale yellowish-greenish slash. Densely brown-pubescent twigs with stellate hairs. Petiole 2 – 3 cm, densely pubescent, with apical pulvinus. Leaves simple, alternate, 10 – 27 x 4 – 11 cm, elliptic – obovate; apex obtuse/acuminate; base rounded – cuneate; margin entire; 6 – 9 pairs of laterals. Venation finely and laxly scalariform. Fruits about 1.5 cm Ø, subglobular, capped by the broad persistent calyx lobes, orange-red when ripe, with white stellate hairs. Note: two new species may have been found in Liberia, one with the rather unique characteristic of slightly peltate leaves. More material needed.
