: Pinnules small and lobate to small and lobed, spaced and marginally decurrent, and not retracted at the base, with a rounded-obtuse apex. Lobate pinnules with slightly asymmetrical margins bearing at least five rounded lobes in which 1–2 rounded lobes are generally poorly developed. Presence of a delicate (poorly developed) basal lobe. Pinna rachis narrow with obvious transverse stripes, invisible at the base, without attenuations at the pinnule apex. Lateral veins regular and thick, except for the rounded obtuse apex of pinnule, the other small pinnules have 2–3 lateral branches directly connected with pinna-rachis and slightly bent outward. Midvein divided more than three times (sometimes more than five times).

The sixth forking occurs very rarely, near the pinnule margin. The lateral veins are regular, strong, and closely spaced, with a vein density that ranges between 20 and 24 per
