- Leaf ovate, 36 mm long, 18 mm wide, coriaceous
and thickly cutinised, widely and shallowly bluntly serrate, base
decurrent, teeth 3 on each leaf side, their size diminishing towards
leaf base, venation pinnate, festooned semicraspedodromous.
Adaxial cuticle thick, ordinary cells 38 μmin diameter, polygonal,
anticlinal cell walls smooth, straight to little curved, abaxial cuticle
thick, ordinary cells the same as in adaxial cuticle, stomata broadly
elliptic, 50 × 40 μm in size, irregularly orientated, anomocytic (to cyclocytic), with a thick stomatal ring inside, I-pieces at poles,
aperture between guard cells linear, short massively cutinised trichomes
simple, subulate, 50–80 μm long and 30 μm thick, on

diameter.
