Diagnosis

Leaflets detached, sessile or exceptionally with very short petiolule, 22–40 mm long, 12–33 mm wide, narrowly to broadly ovate, base asymmetrical, rounded to cuneate, apex broadly acute, margin irregularly, simple bluntly serrate except entire-margined base, teeth simple, shallow asymmetrically rounded, venation semicraspedodromous, craspedodromous, primary vein straight or slightly curved, secondary veins in up to seven pairs with single intersecondaries, looping widely along the margin, lateral veinlets entering the margin into teeth, tertiary veins forming asymmetrical meshes with higher-order vein matrix. Epidermal structure of the holotype: adaxial cuticle smooth, ordinary cells polygonal, 25–40 μm in diameter, anticlinal walls slightly bent, simple thin trichomes up to 150 μm dispersed on veinlets, abaxial cuticle smooth, ordinary cells with curved or bent anticlinal walls, mostly 30 μm in diameter, over veins quadrangular, 12–15 μm wide, 25–75 μm long, solitary elliptical thin-walled trichome bases 25 × 15 μm in size, stomata irregularly disposed, elliptic, irregularly sized, average 25 μm long, 15 μm wide, ? anomocytic, stomatal ledges slightly thickened, aperture boat-shaped, slit linear.
