Leaves: petiole 2–8 mm long, 1–2 mm diam; lamina narrowly elliptic to elliptic, 5–15 by 1.5–4 cm (leaf index 2.3–5.3), chartaceous, not verruculose, pale brown above, brown below, densely covered with erect hairs to glabrous above, densely covered with erect hairs below, base acute, apex acute, primary vein impressed above, secondary veins distinct, 10–14 on either side of primary vein, raised above, smallest distance between loops and margin c. 1 mm, tertiary veins raised above, reticulate. Flowers solitary in axils of leaves; flowering and fruiting pedi- cels 5–25 mm long, 1–3 mm diam, fruiting pedicels rarely to c. 45 mm long, densely to sparsely covered with erect, brown hairs, articulated at 3–15(–20) mm from the base, bracts 3–5, soon falling, basal bracts broadly elliptic, 1.5–2 mm long, upper ones elliptic to elliptic-obovate, to c. 7 mm long; flower buds depressed ovoid; sepals free, broadly to shallowly ovate-triangular, 2–5 by 3–4 mm, reflexed, outer side densely cov- ered with erect, curly, pale brown hairs; petals pale green in vivo, narrowly elliptic to elliptic, 6–20 by 4–10 mm, outer side densely covered with erect, curly, pale brown hairs to glabrous; stamens 1–1.5 mm long, connective shield hairy. Monocarps 15–40, blackish purple in vivo, black in sicco, ellipsoid, 5–8 by 4–5 mm, glabrous, apex apiculate (apiculum c. 0.5 mm long), wall c. 0.3 mm thick, stipes 5–10 by 1 mm.

Distribution — Brazil ( Bahia, Distrito Federal, Espírito Santo, Goiás, Mato Grosso, Minas Gerais, Pernambuco, Rio de Ja- neiro, São Paulo).
