- Leaf with wide elliptic shape; obtuse asymmetric base with a concave side; toothed margin, small thin salicoid teeth oriented toward the external part of the leaf; imperfect acrodromous venation, since one of the principal lateral veins forms a narrow arc with the adjacent secondary vein, straight evident midvein, two principal lateral veins, IAMVs of 37 and 31, two pairs of secondary veins, IAMV 50 (31–66); numerous sigmoid intersecondary veins connecting the proximal zone of the principal lateral veins with the midvein; abundant percurrent tertiary veins with curved trajectory toward the apex in the intercostal areas; quaternary veins forming a regular reticulate pattern.
