Stipule to 4 mm long, puberulent on both surfaces, linear, fugaceous. Leaves 6-10 by 2.5-4 cm, coriaceous, ovate-lanceolate, sometimes sparsely cream lepidote beneath; base obtuse or broadly cuneate; apex to 2 cm long caudate; nerves 8-10 pairs, slender; midrib elevated beneath, depressed above, at c. 40°-50°, well spaced, curved, with or without minute axillary domatia; tertiary nerves very slender, scalariform, at 90°; petiole 0.7-1 cm long, slender.
