- Diagnosis
- Leaves long petiolate, petiole > 15 mm long, lamina
ovate, 80 mm long, > 40 mm wide, entire-margined, apex
bluntly acute, base widely cuneate, venation camptodromous,
primary vein stout at base, much thinner apically, secondary
veins irregularly spaced, more closely spaced at base than towards
apex, bent, forked and looping at margin, intersecondaries
rare and single, intercostal tertiary veins straight, perpendicular to
secondary veins. Adaxial cuticle smooth, hairless, polygonal
cells with straight anticlines without thickenings 20–30 μm in
diameter, abaxial cuticle very thin, ordinary cells domed, stomata
not sunken, brachyparacytic, guard cell pairs broadly elliptic to
transversally elliptic, 15 μm long, stomatal ledges slightly thickened
in the middle, forming spindle-shaped narrow outer aperture.
Mesophyll tissue filled with lens-shaped oil cells 25–50 μm
in diameter.
