- Diagnosis
- Leaf lamina entire, oval, length-width
ratio 1.8. Lamina base round or broadly cuneate, occasionally asymmetric, apex acuminate. Leaf margin
toothed. Venation actinodromous. Basal veins deviate
suprabasally, going up to 1/2 of leaf lamina length and
equal to first pair of secondary veins; agrophic veins,
4–8, present. Secondary veins three to six pairs. Tertiary veins thin, weakly convex or sinuous, opposite or
alternate percurrent. Higher-order veins form reticulum of polygonal areoles with dichotomizing vein.
Upper leaf surface epidermis consists of polygonal
elongate cells with weakly undulate or straight anticlinal walls. Lower leaf surface epidermal cells polygonal, elongate with undulate anticlinal walls. Stomata
anomocytic with six or seven subsidiary cells. Epidermis of upper and lower leaf surfaces bears trichome
bases developing on several cells.
