Original diagnosis/description
Leaves ovate to ovate-lanceolate, apex shape long and acuminate, base shape convex slightly. The leaf margin was entire. Primary venation pinnate, Secondaries brochidodromous. Secondary angles to midvein 40–60°. Intersecondary vein present. The basal veins of the intersecondary veins parallel to the secondary veins. Epidermal cells were irregular and polygonal in shape, anticlinal walls undulated shallowly. Trichome multicellular. Stomata cyclocytic.
