Tree, 2-8 m tall, d.b.h. unknown; stilt roots or buttresses absent, slash yellow. Indumentum of simple, bifid, fasciculate or stellate hairs; old leafless branches glabrous, young foliate branches tomentose. Leaves: petiole 3-8 mm long, 1-2 mm in diameter, tomentose to sparsely pubescent, cylindrical, blade inserted on top of the petiole; blade 10-29.5 cm long, 3.5-10.5 cm wide, elliptic to obovate, apex acuminate to mucronate, acumen 1-2 cm long, base cuneate to rounded to acuminate, subcoriaceous, above glabrous when young and old, below pubescent when young and old, hairs simple, bifid and stellate pointing in all directions, concolorous; midrib sunken or flat, above glabrous when young and old, below pubescent when young and old; secondary veins 9 to 13 pairs, glabrous below; tertiary venation intermediate. Individuals bisexual; inflorescences ramiflorous on young foliate branches, leaf opposed or extra axillary. Flowers with 6 perianth parts in 2 whorls, 1 per inflorescence; pedicel 4-14 mm long, ca. 2 mm in diameter, sparsely pubescent; in fruit ca. 10 mm long, ca. 2 mm in diameter, pubescent; bracts 2, one basal and one upper towards the lower half of pedicel, basal bract 2-4 mm long, 2-3 mm wide; sepals 3, valvate, free, 5-9 mm long, 3-4 mm wide, triangular, apex acute, base truncate, pubescent outside, glabrous inside, margins flat; petals free; outer petals absent; inner petals 3, valvate, 12-26 mm long, 7-12 mm wide, ovate to inversely Y-shaped ridged, apex acute, base broad and concave, yellow-green, margins flat, pubescent outside, pubescent towards margins inside; stamens 60 to 125, in 5 to 6 rows, ca. 2 mm long, linear; connective flattened, glabrous; staminodes absent; carpels free, 20 to 35, ovary ca. 3 mm long, stigma lobed, pubescent.

Notes.
Annickia letestui is characterized by having tomentose young foliate branches and petioles, the lower side of the leaf blades are pubescent with appressed or erect hairs that are simple, bifid, fasciculate or stellate, pointing in all directions. Versteegh and Sosef (2007) note that the indumentum is quite variable within this species, even within individuals, varying from short and appressed to erect and longer hairs.
Vernacular names are likely to apply to other species of the genus.
