Diagnosis
ReferenceDiagnosis
R. S. Hill and H. E. Merrifield 1993Leaves about 6 cm long, 2 cm wide, elliptical. Secondary venation pattern strongly developed, with an intramarginal vein just inside
the margin; secondary vein course sub-parallel and branching. Tertiary veins random reticulate. Stomates restricted to one leaf surface, with an anomocytic subsidiary cell arrangement. Epidermal cell walls highly sinuous, two-~elled oil glands prominent. Trichomes absent. On the non-stonmtiferous surface epidermal cells may be slightly sinuous, or more often straight-walled. Trichome bases with a unicellular foot cell embedded in the epidermis and radiating surrounding cells are relatively common. Trichomes not preserved.
