- Diagnosis
- Fronds at least bipinnate. Pinnae of last order small, alternately pinnate. Pinnules of subtriangular shape. Adult pinnules sphenopteroid to pecopteroid. Margins of pinnules lobate; adult pinnules become almost entire-margined. Bases of pinnules coalescently fused and form limb (wing) of pinna rachis. Apical part of pinna rachis and apical lobes of pinnules can be modified into terminal tendrils or climbing hooks. Midvein of pinnules slightly waving, undulating or straight. Lateral veins once to twice dichotomizing. Leaves amphistomatic. Common cells of epidermis long, of trapezioid to rectangular shape, with straight to slightly curved radial (centriclinal) walls. Long unicellular hairs (trichomes) present. Stomata monocyclic to incompletely dicyclic, with two proximal papillae disposed opposite to each other on opposite subsidiary cells. Periclinal walls of subsidiary cells slightly thicker than periclinal walls of common epidermal cells.
