Guatteria macropus Mart.(1841) 28,t. 8; R. E.Fr. (1939) 337. — Type: Martius 712 (holo M; iso B, BM, BR 2 sheets, F, G 2 sheets, HAL, K, L, MO, NY, P, W), Brazil, Bahia, Ilhéus, Fazenda Almada , 9 Jan. 1837 .

Tree or shrub 2–13 m tall, 5–15 cm diam; young twigs densely covered with erect, brown hairs, soon glabrous. Leaves: petiole 2–10 mm long, 1–2 mm diam; lamina narrowly elliptic to elliptic, 5–18 by 1.5–6.5 cm (leaf index 2.6–7(–10.7)), chartaceous, rather densely verruculose or not verruculose, brown above, pale brown below, glabrous above, densely covered with erect hairs to glabrous below, base obtuse to acute, apex acuminate (acumen 10–15 mm long), primary vein impressed above, secondary veins indistinct, 9–14 on either side of primary vein, raised above, smallest distance between loops and margin 2– 5 mm, tertiary veins raised above, reticulate. Flowers solitary in axils of leaves; pedicels 60–120 mm long, c. 1 mm diam, fruiting pedicels to c. 1.5 mm diam, sparsely covered with appressed, brown hairs to glabrous, articulated at 0.1–0.3 from the base, bracts 1–3, soon falling, 5–20 mm long; flower buds broadly ovoid; sepals free, broadly triangular to triangular, 5–10 by 3–9 mm, reflexed, outer side rather densely to sparsely covered with erect hairs; petals pale green or cream in vivo, narrowly elliptic to elliptic, 10–30 by 5–13 mm, outer side densely to sparsely covered with erect, curly, brown hairs; stamens c. 2 mm long, connective shield papillate. Monocarps 15– 25, blackish purple in vivo, black in sicco, ellipsoid, c. 10 by 5 mm, glabrous, apex apiculate (apiculum 0.5 mm long), wall c. 0.3 mm thick, stipes c. 10 by 1 mm. Seed ellipsoid, c. 10 by 5 mm, dark brown, pitted, raphe raised.

Distribution — Brazil (Bahia, Espírito Santo, Minas Gerais, Pará).

Habitat & Ecology — In non-inundated, Atlantic rain forest or periodically inundated forest, on clayey soil. At elevations of 10– 750 m. Flowering: November to July; fruiting: May to September.

Vernacular names — Brazil: Pindaíba (Sant’Ana et al. 183), Pindaíba-preta ( Harley et al. 18351).

Note — Guatteria macropus is characterized by usually very long floral pedicels even up to 120 mm long, causing the flowers to hang from the branches. It resembles G. australis by the leaf size. However, G. macropus can be distinguished by often longer floral pedicels. Guatteria candolleana differs from this species by the cordate leaf base.
