Scandent shrubs ca. 2 m tall, stem cylindrical, tomentose. Leaves alternate, petiole 5–6 mm, tomentose, lamina 2.5– 5.5 × 1.8–2.5 mm, obovate to elliptic, apex obtuse to rounded, rarely cuneate, base cuneate, margin entire, chartaceous, upper surface pilose to puberulous, lower surface pilose. Inflorescences in panicles. Flowers 2.8–3 mm long., greenish white, sessile, subtended by one bract at base 0.8–1 × 0.7–0.8 mm, ovate, externally pubescent, internally glabrous, sessile, ciliate, apex rounded, and two narrow bracteoles ca. 1 × 0.6 mm, ovate, ciliate, with both surfaces glabrous; sepals glabrous on both surfaces, one lower external sepal 1.5–1.8 × 1–1.6 mm, ovate-oblong, two upper external sepals 1.3–1.7 × 1.2–1.6 mm, ovate, two internal sepals (wings) 1.5–2.5 × 1.7–2 mm, obovate; keel (excluding claw) 2.2–2.6 × 1.5–2.2 mm, glabrous on both surfaces; claw ca. 0.5 mm long, glabrous; lateral petals 1.8–2 × 1–1.3 mm, asymmetrical, apex rounded, externally glabrous, inner surface puberulous in mid-portion; filaments fused into a sheath 1.5–2 × 2–3 mm, internally glabrous, externally pubescent at apex, free portions 1.5 mm, glabrous; rudimentary petals ca. 0.2 × 0.2 mm, ovate, glabrous; style 2.2–2.5 mm long, arched, laterally compressed, glabrous; ovary 0.7–1 × 0.6–1 mm, oblong, glabrous (lacking a trichome ring at base). Capsules 9.5–10 × 3–5 mm, obovate, apex emarginate, glabrous. Seeds 5 mm long (with trichomes 8 mm long). ( Fig. 1B View FIGURE 1 ).
Notes: — Bredemeyera atlantica morphologically resembles B. hebeclada (DC.) J.F.B. Pastore (2010: 314) and B. laurifolia (A.St.-Hil. & Moq.) Klotzsch ex A.W. Bennett (1874: 52) by the sessile flowers and pyramidal inflorescences. However, the new species is readily distinguished by its smaller flowers (2.8–3 mm long in B. atlantica vs 4 mm long in B. hebeclada and 5.5 mm long in B. laurifolia ), and by the absence of a trichome ring at the ovary base, present in B. hebeclada and B. laurifolia ( Fig. 2 View FIGURE 2 ).
Distribution: — Bredemeyera atlantica occurs in Atlantic forest of the Brazilian states of Espírito Santo and Rio de Janeiro ( Fig. 3 View FIGURE 3 ).
