Bertolonia vitoriana Bacci & Michelangeli (in Bacci et al . 2018: 788 ). Figures 10d , 19 . Herbs 20–40 cm tall, terrestrial, seldom epiphytic. Stem 1–3 mm wide, quadrangular or rounded, densely glandulosepunctate (trichomes less than 0.1 mm long). Leaves opposite; petioles 0.6–5.3 cm long, quadrangular, moderately to densely glandulose-punctate; blades 6.8–14.2 × 3.3–7 cm , flat, seldom slightly undulate, lanceolate to narrowly ovate, base widely rounded or narrowly rounded, apex acute, margins denticulate, sparsely ciliate, adaxial surface dark green, sparsely glandulose-punctate (trichomes less than 0.1 mm long, brownish), abaxial surface vinaceous, sparsely glandulose-punctate (trichomes less than 0.1 mm long, brownish), main veins 3, plus two pairs that do not reach the leaf apex, suprabasal. Inflorescences terminal, pseudo-lateral when old, 5.5–9.5 cm long ( 6–11 cm long in infructescences), branches moderately glandulose-punctate when young, glabrous when old. Bracts 1.3–1.7 mm long, elliptic, apex acute, margins eciliate, both surfaces glandulose-punctate; bracteoles 0.9–1 mm long, elliptic, seldom obovate, apex acute, both surfaces glandulose-punctate. Hypanthium 2.1–2.6 × 1.3–2 mm , obconic, glandulose-punctate. Sepals ovate, apex acute, margins entire, eciliate, both surfaces glandulose-punctate. Petals 7–9.5 × 4.5–7 mm long, white, elliptic, base cuneate, apex acute, margins entire, eciliate, both surfaces papillose, otherwise glabrous. Stamens 4.2–6.1 mm long; filaments 1.6–3.5 mm long; anthers 2.1–2.7 mm long, yellow, lanceolate, slightly undulate; pore rounded, non-thickened margins, introrse; connective shortly prolonged (less than 0.4 mm ), dorsally thickened. Style 3–6 mm long, curved, glabrous. Fruits 0.5–0.6 × 0.7–0.9 cm . Seeds reniform. FIGURE 19. Bertolonia vitoriana . A. Fertile branch. B. Trichomes on the petiole. C. Leaf base, abaxial surface. D.

Conservation Status: — The species has been collected several times in only one locality in the municipality of Camacan, in the “Reserva Particular do Patrimônio Natural Serra Bonita”. Bertolonia vitoriana has an EOO of 3 km ² and AOO of 1 km ², and should be classified as “Critically Endangered” (CR), following IUCN (2017) categories. Notes: — Bertolonia vitoriana is endemic to Bahia , occurring in montane rainforests ( Fig. 13g ), on shaded and moist slopes. Collected with flowers from November to January, and fruits from November to April and June. Bertolonia vitoriana can be distinguished by the stem, petioles, leaf blades and hypanthium only glandulose-punctate, leaves with flat surfaces and the suprabasal inner pair of veins, and flowers with white petals and yellow anthers. Bertolonia vitoriana is similar to B. bullata . For more details see the notes under B. bullata in Bacci et al . (2018) and Table 1 .
