2.1. Huberia ovalifolia Candolle (1828: 167) . [ Figs. 3c–d View FIGURE 3 , 4k–o View FIGURE 4 ]

Trees or treelets 3–15 m, apparently glabrous; indumentum of the branches, leaves, inflorescences, pedicel, hypanthium and calyx glandular-punctate. Petioles 1.2–3.5 cm long; blade 5.7–18 × 2.5–8 cm, chartaceous, ovate or elliptic, base obtuse to acute, apex obtuse to acute, margin entire; acrodromous basal veins 3. Inflorescences 5.4–15.2 cm, terminal; bracts 1.5–2.4 × 5–9 mm, bracteoles 0.5–1 × 0.1–0.5 mm, both persistent, linear-triangular. Flowers 4-merous; pedicel 1.1–2 cm long; hypanthium 3–10 × 2.2–2.9 mm, tubulose; calyx persistent, lacinias unilobed, 1.8–2.7 × 1.6–3 mm, broadly ovate, apex rounded; petals 11–26 × 6–17 mm, white, yellow at the base, apex rounded-acuminate, glabrous; stamens isomorphic, subequal in size, yellow, becoming reddish at maturity; filaments 5–9 mm long; anthers 11–12 mm long, pore terminal, connective not prolonged nor thickened bellow the thecae, dorsal appendage 4.2–9 mm long, linear; ovary 4.7–6.5 × 1.9–4 mm, 2/3-superior free inside the hypanthium, 1/3-inferior adnate at the base, 4-celled, glabrous; style 1.6–2.6 cm long, glabrous. Capsule 12–14 × 6–9 mm, ruptidium type, urceolate, ovate, polyspermous; seeds 2.5–5 × 0.5–0.9 mm, winged, linear to oblong, dorso-ventrally flattened.

Distribution:—Endemic to Brazil and Atlantic Forest Biome, occurring from the state of Bahia to São Paulo ( Chiavegatto & Baumgratz 2012). It is categorized as Vulnerable to the municipality of Rio de Janeiro ( Baumgratz 2000).

Comments:— In Marambaia Island , H. ovalifolia occurs in Restinga Forest and Dense Submontane Ombrophilous Forest. It can also be distinguished by the long floral pedicel (1.1–2 cm); flowers with yellow stamens, thecae become reddish to vinaceous after fertilization, connective with a linear dorsal appendage, and capsules of the ruptidium type.
