Description

HABIT. Tree, to 4–12 m tall, DBH to (5–) 10–40 cm; many-branched, branches and twigs slightly tomentose or glabrous.

LEAVES. With 2–3-fid stipules, divided for part of their length into mostly ovate-lanceolate lobes, 5–12 mm long, 2–3 mm wide at base, sharply pointed, glabrous or slightly tomentose; petiole 0.5–1.8 cm long, almost glabrous with rusty indumentum; leaf blade usually drying greenish-brown, oblong-oblanceolate to oblong-elliptic, 10–35 cm long, 3.5–14 cm wide, sub-leathery, glabrous above, mostly glabrous below apart from some scattered single hairs on midrib or some scattered stellate hairs on blade, apex acute to slightly acuminate, base cuneate to rounded, often asymmetric, joining the petiole at different points on the two sides of the lamina, margin coarsely and irregularly toothed with large (up to 1 cm), jagged teeth, with domatia formed of long simple hairs in nerve axils below (but can be lacking).

INFLORESCENCE. An axillary or terminal cyme of 5–7 flowers, usually rather condensed; peduncle 0.7– 2 cm long, glabrous; involucral bracts 5–6, ovate-lanceolate, 3–5 mm long, greyish tomentose, not enveloping the young buds, usually falling off early.

FLOWERS. Pedicellate; pedicels thick, 2–6 mm long, slightly tomentose; buds subglobose, greyishtomentose; sepals white or cream to slightly pale pink, fleshy, oblong-lanceolate, 1–1.4 cm long, 4–6 mm wide, fringed at apex, tomentose; petals oblong-roundish, 2.4–2.8(–4) mm long, 2–2.4 mm wide; ovary 6–10-locular.

FRUITS. Subglobose to elliptic, 10–25 cm long, 8–20 cm wide, flattened at base and apex, obscurely grooved, glabrous.

SEEDS. Obovoid, 1.8 m long, 8 mm wide.

Distribution (see Fig. 7 )

Angola, Cameroon, Central African Republic, Congo, Democratic Republic of Congo, Equatorial Guinea, Gabon, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, Togo, Uganda.

Habitat

Terra firma forest and occasionally recorded from seasonally flooded forest. At altitudes of 350–1250 m a.s.l.

Phenology

Flower: February–April, September, fruit: February, July, October–November.

Proposed IUCN status

Least Concern (LC). Desplatsia dewevrei has an EOO of 4 271 669 km 2 and an AOO of 572 km 2, with a wide distribution across the forests of West and Central Africa. There are no major threats. Several collections are from protected areas which give this species some level of protection. Our assessment as LC is in agreement with the IUCN Red List assessments of threatened species (BGCI and IUCN SSC Global Tree Specialist Group 2019a).

Notes

Two sheets of Dewèvre 901 collection are available at BR, here we selected the better conserved sheet as lectotype for Grewiopsis dewevrei .

The sheet with fruits and flowers out of the two sheets found in Paris of the Trilles 189 collection cited in the protologue for Grewiopsis trillesiana syn. nov. ( Chevalier 1912) was chosen here as lectotype for that name.

Out of the syntypes available at K, P and WAG, a specimen with flowers we have seen at K was chosen as lectotype for D. lutea .

Out of the two specimens available from the Chevalier 16272 collection for D. acuminata , the fruiting specimen was chosen as lectotype.
