Type: Congo-Kinshasa, Kasai, Kiyaka, Kwango, Lutete forest (BR, holo.; K!, iso.) .
Morphology General Habit
Epiphyte, semi-erect or trailing; stems to 80 cm long, up to 7 mm thick, branched, rooting at the nodes, woody at the base.
Morphology General Indumentum
Indumentum of peltate scales with fimbriate margins.
Morphology Leaves Stipules
Stipules narrowly triangular to triangular, 0.8–1.5 cm long, caducous, apex acuminate, indumentum present on outside.
Morphology Leaves
Leaves drying papery, ± symmetrical, narrowly elliptic to narrowly ovate, 3.5–15 × 1.3–5 cm, base obliquely and weakly cordate, margin entire to remotely denticulate, apex acute to shortly acuminate, glabrous above, sparsely scaly beneath, dense on venation; venation pinnate; petiole 0.8–3.5 cm long, puberulous.
Morphology Reproductive morphology Inflorescences
Inflorescence axillary, a bisexual dichasial cyme, 3–flowered with 2 lateral ♀ and a central ♂; peduncle 2–20 mm long, densely scaly; each ramification subtended by a pair of bracts; bracts fused into a chartaceous caducous bifid ochrea, 3–7 mm long, splitting with age; small opposite bracts supporting the female flowers, looking like bracteoles; pedicels (♂ only) 2–14 mm long; bracteoles absent.
Morphology Reproductive morphology Flowers
Male flowers: tepals 4, free, white or pinkish, the outer ovate, 7 × 3 mm, the inner narrowly ovate, 3–4.5 × 1.5–2 mm; stamens 9–20, filaments fused at the base to form a column, anthers oblong, 1–1.5 mm long. Female flowers: sessile, tepals 4, free, colour and shape as in the male flowers, the outer 0.6–1 × 0.3–0.6 cm long, the inner 0.4–0.7 × 0.15–0.4 cm; ovary fusiform, 8–13 mm long, without wings, 3locular; placentation unknown, probably septal; styles 3, forked at the apex, glabrous, not persistent in fruit; stigmatic band yellow, horseshoe-shaped, weakly twisted.
Morphology Reproductive morphology Fruits
Mature fruits sessile (2 per infructescence), red, fleshy, fusiform, 2.2–3.9 cm long, 0.2–0.4 cm in diameter, terete in cross section, dehiscence unknown but probably by one or more longitudinal slits, with a distinct apical scar where tepals and styles have fallen off.
Presumably moist forest; 1100–1150 m.
Probably least concern (LC).
