- Leaf simple, petiolate, petiole thin, lamina
chartaceous, shallowly trilobate, apex broadly acute, margin
shallowly bluntly simple dentate-lobed, venation basal
actinodromous, midrib thin, only slightly thicker than secondaries,
basal veins departing at an angle of 40°, higher secondary
veins subparallel and widely irregularly spaced, simple,
looping and curved along margin, tertiary veins irregularly
reticulate. Adaxial and abaxial cuticles thin, adaxial cuticle
faintly striate, unspecialised cells irregularly polygonal, 25–
50 μm in diameter, with curved anticlinal walls, abaxial cuticle
densely finely papillate, papillae granular, ca. 8 μm in
diameter, papillae larger towards leaf margin, densely distributed
on stomatal areas, forming rings around hardly visible
elliptic stomata, stomata 15 μm long and 10 μm wide.
