- Diagnosis
- Leaves amphistomatic, cells irregular with rounded corners, uniformon thewhole leaf blade, sometimeswith central papillae. Stomata scattered, 5–7 subsidiary cells with or without papillae directed towards stomatal pit. Leaves margins entire, scarious, often turning into fringes which form microscopic, unicellular teeth near the apex. Ovules smaller than lobes, oval in outline. Seeds almost as large as lobes, broad oval in outline, with slightly expanded micropylar end. Bract's top reaches to the basal parts of ovuliferous scale lobes. Microsporophyll distal blade nearly rhomboidal in shape, with a sharp apex and scarious margins. Pollen grains circular in polar view to oval in equatorial or oblique view. Exine surface rugulate.
