- Diagnosis
- Elliptic-shaped lamina, 16.0–28.0 mm in length, 5.0–7.0 mm in width, and a length/width ratio of 3.2–4.0 : 1; petiolate 1.5–2.0 mm, rounded and acute base; acute apex (35), toothed margin composed of small and irregular
salicoid teeth, small and spaced salicoid teeth; pinnate venation, straight and stout midvein, seven to nine pairs of slightly curved secondary veins, with a pronounced eucamptodromous development toward the margin and with markedly thinner diameter compared with that of the midvein; insertion
angle to the midvein (IAMV) 39 (24–58); tertiary percurrent veins are scarce and may form some narrow arcs with respect to the adjacent secondary veins; there is no clear differentiation between third- and fourth-order veins that form a random reticulate pattern.
