An often cauliflorous tree or shrub 3–10(–18) m tall, 6–18 cm diam; young twigs densely covered with erect, brown hairs. Leaves: petiole 6–12 mm long, 2–5 mm diam; lamina narrowly elliptic to narrowly obovate, 17–40 by 5–15 cm (leaf index 1.5–3.8), chartaceous to coriaceous, not verruculose, blackish green above, brown below, sparsely covered with erect hairs to glabrous above, densely covered with erect hairs to sometimes glabrous below, base obtuse to attenuate, apex acuminate (acumen 10–20 mm long), primary vein impressed above, secondary veins distinct, 10 –20 on either side of primary vein, raised or impressed above, smallest distance between loops and margin 2–4 mm, tertiary veins raised above, reticulate. Flowers solitary in axils of leaves or mostly in 1–2(–more?)- flowered, densely clustered inflorescences on the stem; pedicels 15–60 mm long, 1–3 mm diam, fruiting pedicels to c. 70 mm long, densely to sparsely covered with erect, brown hairs, articulated at 0.1–0.2 from the base, bracts 2–3, soon falling, 5–6 mm long; flower buds broadly ovoid; sepals free, broadly to shallowly ovate-triangular, 5–10 by 7 mm, reflexed, outer side densely covered with erect hairs to glabrous; petals cream or yellow in vivo, elliptic to ovate, 13–20 by 6–12 mm, outer side sparsely covered with erect, brown hairs; stamens c. 2 mm long, connective shield papillate. Monocarps 25– 55, green, maturing reddish to purple-black in vivo, black in sicco, ellipsoid, 8–12 by 5–7 mm, glabrous, apex apiculate (apiculum 0.5–1 mm long), wall 0.1–0.3 mm thick, stipes 10–25 by 1 mm. Seed ellipsoid, 8–12 by 5–7 mm, brown, pitted, raphe raised.

Note — Guatteria ferruginea is the only cauliflorous representative of this genus in the Atlantic forests of Brazil. It is characterized by large leaves (17–40 by 5–15 cm), usually densely covered with erect, brown hairs on the lower side, and outer side of sepals and petals also often covered with erect, brown hairs. Guatteria ferruginea is similar to G. pogonopus . It shares the large leaves, but the pedicels in the latter are much shorter. However, G. pogonopus has glabrous leaves and, moreover, it is not cauliflorous.
