- Diagnosis
- Frond at least once pinnate. Pinnae basically rounded and apically pointed, with entire margins. Lateral veins generally arising from the midvein by an acute angle curving until nearly perpendicular to the midvein. Veins usually fork once near the midvein and sometimes once more near the margin.
Venuli recurrentes absent. Fertile pinnae identical in shape and size to sterile ones. Length of synangia occupies about oneeighth (in the middle) to one-sixteenth (in apical region) of the pinna width. In situ spores monolete.
