Herbs 14–30 cm tall, terrestrial, seldom rupiculous. Stem 2–6 mm wide, rounded to quadrangular, moderately glandulose-punctate (trichomes less than 0.1 mm long). Leaves opposite; petioles 1–12.4 cm long, rounded to quadrangular, moderately to densely glandulose-punctate, sometimes glandulose-villose (trichomes 0.9–1.5 mm long); blades 3.9–17.2 × 2.5–11.5 cm, flat, elliptic to widely ovate, seldom lanceolate, base cordate to subcordate, apex acute to rounded, seldom acuminate, margins entire to slightly crenate, moderately to sparsely ciliate, adaxial surface dark green, sometimes white or light green along the primary vein, moderately to sparsely glandulose-punctate and sparsely glandulose-villose (trichomes ca. 1 mm long, brownish), abaxial surface light green to vinaceous, sparsely to densely glandulose-punctate and sparsely glandulose-villose (trichomes 0.6–1 mm long, brownish), main veins 3 or 5, plus one or two pairs that do not reach the leaf apex, basal. Inflorescences terminal or pseudo-lateral, 2.1–13 cm long (6–27 cm long in infructescences), branches densely glandulose-punctate, seldom moderately glandulose-villose, glabrous when old. Bracts 2–3 mm long, lanceolate, apex acuminate, margins ciliate, both surfaces glandulose-punctate; bracteoles 0.7–0.9 mm long, lanceolate, apex acuminate, both surfaces glandulose-punctate. Hypanthium 1.7–4.4 × 1.2–3.3 mm, shortly terete to obconic, glandulose-punctate. Sepals ovate to widely ovate, seldom elliptic, apex acuminate, margins entire, ciliate, both surfaces glandulose-punctate. Petals 8–9.5 × 3.5–7 mm, pink, seldom lilac, elliptic, base cuneate, apex acuminate or acute, margins entire, eciliate, both surfaces papillose, otherwise glabrous. Stamens 3.5–9.8 mm long; filaments 1.4–5.2 mm long; anthers 2–5 mm long, cream colored, narrowly oblong, lanceolate or sometimes slightly falciform, surface flat or sometimes slightly undulate, pore rounded, non-thickened margins, introrse; connective shortly prolonged (ca. 0.2 mm), dorsally bilobed. Style 6–12 mm long, straight or slightly curved, glabrous. Fruits 0.4–0.7 × 0.7–1.1 cm. Seeds widely fusiform.

Conservation Status: — Bertolonia carmoi has an EOO of 28,835 km ² and AOO of 28,724 km ², and should be classified as “Near Threatened” (NT), following IUCN (2017) categories. This species has been found mainly in private properties, but also within the conservation units “Área de Proteção Ambiental do Pratigi”, “Estação Ecológica Wenceslau Guimarães”, “Parque Estadual Serra do Conduru”, “Reserva Biológica de Una” and “Reserva Particular do Patrimônio Natural Água Branca”.
Notes: — Bertolonia carmoi is endemic and widely distributed in Bahia, occurring in lowland rainforests and montane rainforests (Fig. 3d). Collected with flowers from July to February and fruits from August to March. Bertolonia carmoi is characterized by the branches, petioles, leaf blades, hypanthium and sepals only glandulose-punctate, the adaxial surface sometimes glandulose-villose, and also by the anthers with a flat surface and an introrse pore. Bertolonia carmoi is similar to B. maculata De Candolle (1828: 114) and B. marmorata, and it can be distinguished by the stem, branches and hypanthium only glandulose-punctate (vs. stem, branches and hypanthium also glandulose-villose or glandulose-pilose in B. maculata and B. marmorata) and petals with an acute apex (vs. apex apiculate with a caducous gland head). For more details see Baumgratz (1990) and Table 1.
