1.2. Clidemia urceolata Candolle (1828: 158) . [ Figs. 3b , 4e–j ]

Shrubs 1.5–2 m; indumentum of the branches, leaves, inflorescences, hypanthium, internal calyx lobes, and fruits moderately to densely setose and glandular-setose, glandular head caducous or not, and stellate trichomes sharply pedicelate. Petioles 0.5–3.1 cm long; blade 4.9–15.6 × 2.2–6.6 cm, papiraceous or chartaceous, ovate, base obtuse, apex acuminate, margin crenulate, ciliolate, adaxial surface bullate, abaxial surface foveolate; acrodromous basal veins 5. Thyrsoids 2.5–8.9 cm long; bracts 2.1–2.3 × 0.3–0.8 mm, bracteoles 1.7–2 × 0.3–0.5 mm, both narrowly triangular. Hypanthium 3–5.8 × 2.1–4 mm, campanulate; inner torus sparsely glandular, sometimes glabrous; calyx with external lobes 3–4.5 × 0.8–2.7 mm, subulate-awned, internal lobes 1.8–3 × 1.8–2.1 mm, wide-ovate, apex rounded to truncateemarginate; petals 3.9–6 × 3–3.5 mm, broadly ovate, apex rounded-emarginate; stamens with filaments 1.9–3.8 mm long; anthers 2.2–4.1 mm long, connective not prolonged, unappendaged; ovary 2–3 × 2–2.2 mm, inferior, 4–5 celled, furfuraceous-stellulate and rare glandular-setulose; style 4.9–8 mm long. Bacidium 3.8–6 × 3–5 mm, subglobose; seeds 0.6–0.9 × 0.4–0.7 mm.

Specimens examined:— 10.II.2000, fl., fr, H.R. P. Lima 344 (RB, RBR) ; 16.II.2004, fr., L.F.T. Menezes et al. s.n. (RBR 7186) ; 22.V.2005, fr., F.C. Nettesheim 123 (RBR) ; 7.IV.2007, fl., fr., K.C.

Distribution:—A widely distributed species from Central America to Brazil, where it occurs from the state of Bahia to Santa Catarina ( Michelangeli & Reginato 2012).

Comments:—In Marambaia, it is found in Shrubby Restinga and Dense Submontane Ombrophilous Forest. It resembles C. hirta by the bullate adaxial leaves surface, yet with moderate to dense cover of numerous setose, glandularsetose and stellate trichomes. Clidemia urceolata may be sometimes mistaken with C. capitellata ( Bonpland 1816: 5) Don (1823: 310) [= C. neglecta Don (1823: 307) ], a related species that differs by its conspicuous bracteoles, and less dense glandular-pubescence ( Wurdack 1971). Additional illustrations in Cogniaux (1883 –1888) and Matsumoto & Martins (2009).
