Stipules narrowly lanceolate to linear, 10 by 3 mm. Leaves thick-coriaceous, rigid, (18-)20-25(-30) by (6-)7-9(-12) cm (index 2.5-3.5), broadest at or slightly below the middle; surfaces discolorous, above glabrous, dark chocolate-brown, glossy, underneath densely yellowish brown to fulvous adpressed stellate hairy; base rounded-acute, top bluntly 1-1½ cm acuminate; midrib and nerves strongly prominent beneath, slightly so to flat above; nerves (14-)15-17(-20) pairs, parallel, at an angle of 45-60°, arcuating but not anastomo sing towards the margin; reticulation dense, scala-riform, distinct beneath; petiole 1-2 cm, 2-3 cm ø, adaxially flat. Inflorescence male or androgynous, densely yellowish brown adpressed stellate hairy; bract and bracteoles thick-coriaceous, linear, 2½-3½ by ½ mm. Male rachis 10-15 cm, 2½-3 mm ø; ♂ flowers in clusters of 3, filaments 3-4 mm, anthers 0.25-0.3 mm long, pistillode globose, c. 1 mm ø.
