Petioles 2.6–7.4 cmlong; blade 20.5–39.1 × 9.1–18 cm, discolour green, abaxial surface sometimes vinaceous to pink when young, chartaceous, elliptic or ovate, sometimes oblong-ovate, base obtuse to rounded or subcordate, apex acute, margin undulate; abaxial surface very sparsely furfuraceous-stellulate or glabrous; acrodromous basal veins 5, or the inner pair up to 10 mmsuprabasal. Thyrsoids of glomerules 14.3–27.1 cmlong, vinaceous; bracts 2.8–2.9 × 1.8–1.9 mm, bracteoles 3–4.9 × 1.5–1.9 mm, both concave, obovate, apex rounded, very early-caducous. Flowers 5-merous, sessile; hypanthium 1.5–2.9 × 1.8–2.5 mm, campanulate; inner torus glabrous; calyx persistent, lobes ca. 1 x 1–1.5 mm, broad-triangular; petals 2.5–3.2 × 1.7–2 mm, white, obovate, apex obtuse to rounded; stamens subisomorphic and subequal in size; filaments 1.8–4.2 mmlong; anthers 2–2.3 mmlong, white, straight, connective slightly prolonged, appendage dorsally truncate and ventrally 2-auriculate, joined together forming a sheat at the thecae base; ovary 0.8–2.5 × 1.3–2.1 mm, almost completely inferior, 3-celled, sparse-glandular; style 1.8–3.5 mmlong, glabrous. Bacidium2.8–3 × 2.9–3 mm, vinaceous to purple-blackness, subglobose, polyspermous (100–150 seeds); seeds ca. 0.3 × 0.2 mm, obtriangular.  Specimens examined:—   10.II.2000, fl., fr.,  H.R.P. Lima  s.n.( RBR10262);   13.I.2004, fl.,  L.F.T.

Silva102( RBR).   Distribution:—This species has a wide distribution, occurring from southern Mexicoand Central America to Paraguai( Almeda 2009). In Brazil, it is found in the Pará, Amazonas, Acre, Rondônia, Mato Grosso, Mato Grosso do Sul, Goiás, Pernambuco, Alagoas, Bahia, Minas Gerais, Espírito Santo, Rio de Janeiro, São Paulo, and Santa Catarina(Goldenberg 2009).   Comments:—In Marambaia, this species occurs in RestingaForest and Dense Submontane Ombrophilous Forest. It can be distinguished by the connective appendage that is dorsally truncate and ventrally biauriculate, to form a sheat at the thecae base. The abaxial surface of young leaves can be vinaceous or rosy, becoming green when mature. Additional illustrations in Baumgratz et al.(2006). [476,829,1022,1048] 2000-02-10 H.
