Diagnosis
Leaves fan-shaped with a long and slender petiole. The basal angle of leaves 110◦–140◦. Lamina radius 2.5–3.2 cm, usually lobed two or three times producing four or six lobes. Lobes obovate with rounded or obtuse rounded apices. Veins branching dichotomously many times at the base of the lobe and running parallel to the lamina margin in the middle of the lobe, then converging near the apex, 12–14 veins per cm in the widest part of the lobe. Resin bodies absent. Leaf sparsely amphistomatic. Upper cuticle with very few scattered stomata. The outer surface of the upper cuticle nearly smooth. Lower cuticle consisting of costal zones with elongated obliquely angled cells and intercostal zones with 7–9 rows of stomata. Stomata haplocheilic, densely and randomly arranged. Subsidiary cells 5–6, with well-developed papillae on the outer surface.
