Tree 3–18(–22) m tall, 13–35 cm diam; young twigs densely to sparsely covered with appressed hairs, soon glabrous. Leaves: petiole 5–10 mm long, 1.5–2 mm diam; lamina narrowly el- liptic, sometimes elliptic, 7–21 by 2–6(–9) cm (leaf index 1.8–6), chartaceous, not verruculose, pale brown to brown on both sides, sparsely covered with appressed hairs to glabrous above, densely covered with appressed hairs to glabrous below, base obtuse, rarely acute, apex acute, primary vein impressed above, secondary veins distinct, 12 –16 on either side of primary vein, raised above, angle of secondary vein with primary vein 40–55°, smallest distance between loops and margin 1–2 mm, tertiary veins raised above, reticulate. Flowers in 1–2-flowered inflorescences in axils of leaves; pedicels 5–25 mm long, 1–2 mm diam, fruiting pedicels 2–3 mm diam, densely to sparsely covered with appressed, brown hairs, finally glabrous, articu- lated at 0.2–0.3 from the base, bracts 2–4, soon falling, 2–4 mm long; flower buds depressed ovoid; sepals free, broadly ovate-triangular, 5–6 by 5–6 mm, reflexed, outer side glabrous; petals cream in vivo, ovate, 10– 25 by 6 –10 mm, outer side densely covered with appressed, brown hairs; stamens c. 1 mm long, connective shield hairy. Monocarps c. 15, green when young in vivo, black in sicco, ellipsoid, 12–14 by 8 mm, gla- brous, apex apiculate (apiculum <1 mm long), wall c. 0.8 mm thick, stipes 2–5 by 1 mm. Seed ellipsoid, 12–14 by 5 mm, orange-brown, pitted to rugulose, raphe raised.
Distribution — Brazil (Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro).
Habitat & Ecology — In non-inundated, Atlantic rain forest or cerrado, on clayey soil. At elevations of 0–1050 m. Flower- ing: throughout the year; fruiting: January, April, May, October, November.
Vernacular names — Brazil: Araticum ( Ramalho & Rodrigues 1594), Conde ( Piratininga 14), Imbuí (R. Guedes 2280, Piratininga 14).
Note — Guatteria campestris is distinct by mostly narrowly elliptic leaves with an obtuse base, with secondary veins forming an angle of 40–55° to the primary vein, which is a narrow angle for the genus. It resembles G. australis in the size and the shape of the leaves (narrowly elliptic to elliptic). However, G. australis has secondary leaf veins forming an angle of 70–90° with the primary vein.
