Diagnosis

Coriaceous leaves, fragmentarily preserved, base acute, lamina possibly elliptic, no apex preserved, margin ? entire, possibly wavy or with single small teeth present ?, midvein stout, no further venation details discernible. Adaxial cuticle: thick; size of non-modified epidermal cells 24–51 μm (37 μm), anticlines straight or sometimes curved, 3–5 μm thick; very rarely one-celled, well-cutinized, round trichome bases present in intercostal areas, outer diameter 17–22 μm (20 μm), trichome base cells sometimes slightly radially elongated; trichomes not preserved; Abaxial cuticle: thick, smooth, almost glabrous, along veins faint parallel cuticular striation; stomatal complexes anisocyclocytic with 3–6 narrow, tangentially elongated, intensively staining subsidiary cells surrounding the stomata; stomata roundish to oval, quite variable in size, 22–43 μm (27–35 μm) long, 22–34 μm (25–30 μm) wide, outer stomatal ledges of the guard cells distinctly thickened, smooth, stomatal aperture 8–26 μm (11–19 μm) long; prominent but short polar I-pieces present, often not reaching the poles, above the guard cells 1–2 concentric striae; size of non-modifi ed epidermal cells 21–57 μm (28–40 μm), anticlines straight, curved to somewhat wavy, about 2 μm thick.
