Diagnosis
ReferenceDiagnosis
R. S. Hill 1986Lamina. Symmetrical, ovate to elliptical. Base highly variable, symmetrical; apex acute, symmetrical. Leaf length 5.5-11.5 cm, width 1.8-5.7 cm. Petiole normal. Venation. Primary vein straight or slightly curved, moderate to stout. Venation pattern eucamptodromous. About 9-13 uniformly curved secondary veins arise from the primary vein at a uniform angle of 33-51°. Simple intersecondary veins rare, or more usually absent. Tertiary veins strongly percurrent Lower epidermis. Non-venous cells irregular,
with a variable number of sides and straight or slightly sinuous walls. Cuticular flange irregularly thickened. Venous cells longer, narrower, and straighter-walled than nonvenous cells. Stomata confined to areoles, oriented at random. Cuticularised secretory irregularly shaped, thickened foot cell and unmodified or somewhat radial basal cells occur commonly over and between veins. Trichomes long, unicellular, thinly cutinised, and tapering to an acute apex. Upper epidermis. As for lower epidermis, except stomata absent and trichome bases occur only over veins and with varying frequency.
