- Diagnosis
- Small to medium-sized bipinnate, rarely pinnate or tripinnate fronds. Fronds overtopping in the apical portion, in some cases with double apical (pseudo-)dichotomies in larger, (partially) tripinnate fronds. Pinnae subopposite to alternate. Primary rachis with intercalary pinnules. Pinnules small, semi-circular, linguiform to elongate linguiform, broadly attached, decurrent to basally fused in the basal and apical frond portions and pinna apices, entire-margined, crenulate to pinnatifid. Pinnules thick and fleshy with rounded apices and a pinnate venation that is usually hidden by the thick cuticle. Leaves amphistomatic, stomata irregularly scattered; stomatal complexes sunken, monocyclic with 4–8 (usually 5–6) subsidiary cells; papillae may be present. Ovuliferous organs consisting of peltate discs with a central stalk and marginal lobes; upper surface with radiating ribs.
