Inflorescence up to 30 cm long and 20 cm wide; peduncle up to 15 cm, peduncle, rachis, branches and pedicels clothed like the twigs. Flowers up to 3.5 mm long and 2.5 mm wide; pedicel up to 2 mm long, pedicel and calyx densely covered with scales like those on the twigs. Petals 5 (or 6). Staminal tube longer than the corolla, obovoid, with a minute pore 0.2–0.3 mm across which is entire at the margin; anthers 5, 1 /3 to 1/2 the length of the tube, ovoid, inserted near the base and included in the tube. Infructescence up to 30 cm long and 25 cm wide, with c. 50 fruits; the peduncle up to 15 cm, peduncle, rachis, branches and fruitstalks with indumentum like twigs.
