Type
Type: Equatorial Guinea, Fernando Po, Mann 314 (K!, lecto.; K!, iso.).
Habit
Epiphytic herb with stems to 2 m long, growing on trees or rocks; stems creeping, rooting at the nodes, not or rarely branched, up to 1.8 cm in diameter, becoming woody with age; indument of translucent sessile peltate-helicoid scales with fimbriate or long dentate margins or stellate hairs.
Stipules
Stipules narrowly ovate to triangular, 3–5 cm long, caducous, boat-shaped, not keeled, apex acute to mucronate, almost glabrous to densely indumented.
Leaves
Leaves thick and fleshy, obliquely ovate to obliquely suborbicular, (8–)14–30 × (6–)10–25 cm, base cordate, margin entire to broadly denticulate (with minute teeth extending from lateral veins), apex commonly shortly caudate to acuminate; venation palmate, glabrescent to sparsely indumented above, glabrescent to densely indumented beneath, particularly on venation; petiole 5–23 cm long, glabrous or evenly pubescent.
Inflorescences
Inflorescence axillary, bisexual, the axes reduced, many-flowered; peduncle (0.5–)1–4 cm long; bracts 2, persistent, subtending and enveloping the inflorescence, overlapping, boat-shaped, 1.5–2.8(–3.5) cm long; bracteoles absent.
Flowers
Male flowers: tepals 2, pink or white, obovate to broadly obovate, 1.6–4.3 × 1.3–4 cm, often with longitudinal dark pink striations; stamens 25–60, filaments free or fused only at the base, anthers oblong, 2.5–4 mm long. Female flowers: tepals 2, pink or white, obovate to nearly orbicular, 1.7–3.3 × 1.4–3.5 cm; ovary shortly stipitate, obovoid, 4-locular, without wings; placentation pseudo-axillary; styles 4, caducous in fruit, forked at the apex, spirally twisted once, with yellow to greenish stigmatic papillae. Male and female flowers with only the free portion of the tepals exserted from the bracts, the base of the tepals fused to form a perianth cylinder up to 16 mm long.
Fruits
Fruits developing within the bracts, mature fruits white to orange, fleshy, baccate, obovoid to globose, 1–1.3 cm long, apiculate at the apex, 4-lobed in cross section, indehiscent.
Ecology
Moist forest, 1200–1800 m.
Conservation
Least concern (LC); widespread.
Note
One of two species in this region characterised by the conspicuous overlapping, boatshaped bracts that envelope the inflorescence and the fruits (the other being B. poculifera). Seeds seen to be dispersed by ants in Cameroon (Plana, pers. obs.). .
Distribution
Flora districts: U2 Range: Cameroon, Gulf of Guinea Islands, Gabon, Congo-Brazzaville, Congo-Kinshasa, Rwanda
