Guatteria oligocarpa Mart. (1841) 33; R. E.Fr. (1939) 406. — Type: Martius 714 (lecto M, selected by Fries 1939; iso B, BM, BR, F, G 2 sheets, HAL, K, L 2 sheets, M 3 sheets, MO, NY, P, S, W), Brazil, Bahia, Ilhéus, Fazenda Almada (‘in sylvis primaevis ad Almada’), Dec. 1818 .

Guatteria cauliflora Mart. (1841) 35. — Guatteria bahiensis R.E.Fr. (1939) 408,f. 10a. — Type: Blanchet s.n. (lecto B, selected by Fries 1939; isolecto BR), Brazil, Bahia, without locality.

Tree or shrub 1.5–15 m tall; 13–35 cm diam; young twigs sparsely covered with appressed hairs, soon glabrous. Leaves: petiole 5–12 mm long, 2–5 mm diam; lamina narrowly obovate to obovate, 11–25 by 4–12 cm (leaf index 1.7–3.8), subcoriaceous to coriaceous, not verruculose, shiny, brown above, dark brown below, glabrous above, sparsely covered with appressed hairs to glabrous below, base obtuse, apex acute to acuminate (acu- men c. 10 mm long), primary vein impressed above, secondary veins indistinct, 10–17 on either side of primary vein, raised above, smallest distance between loops and margin c. 2 mm, tertiary veins raised above, reticulate. Flowers solitary in axils of leaves; pedicels 5–20 mm long, c. 2 mm diam, fruiting pedi- cels to c. 3 mm diam, sparsely covered with appressed, brown hairs to glabrous, articulated at c. 0.2 from the base, bracts not seen; flower buds depressed ovoid; sepals free, broadly ovate-triangular, 5–7 by 5–8 mm, reflexed, outer side glabrous; petals cream or yellow in vivo, elliptic, 12– 20 by 6–11 mm, outer side densely covered with curly hairs to glabrous; stamens c. 2 mm long, connective shield hairy. Monocarps 10–35, dark purple in vivo, black to brown in sicco, globose, 12–20 by 10–13 mm, glabrous, apex rounded, wall c. 1 mm thick, stipes 5–30 by 1 mm. Seed ellipsoid, c. 10 by 7 mm, brown to dark purple, smooth to slightly pitted, raphe slightly raised.

Distribution — Brazil (Alagoas, Bahia).

Habitat & Ecology — In non-inundated, Atlantic rain forest or periodically inundated forest, on clayey to sandy soil. At elevations of 0–1070 m. Flowering: throughout the year; fruiting: throughout the year.

Vernacular name — Brazil: Pindaíba-cabo-de-rodo (L.A.M. Silva et al. 2463).

Note — Guatteria oligocarpa is characterized by medium-sized to large, subcoriaceous to coriaceous leaves, and globose monocarps and seeds not adhering to the monocarp wall in sicco. Vegetative plants of G. oligocarpa may have larger leaves than just decribed, and then resemble G. pogonopus , but the latter has ellipsoid instead of globose monocarps, and seeds remain stuck to the monocarp wall in sicco.
