- Sporophylls distichous, alternate; proximal part of sporophyll
semicircular, dichotomous, distal part upturned. Sporangia
abaxial, arranged in a single crescent. Microsporangia with proximal

petiole and rachis of correlated foliage) bilaterally symmetrical,
sporophyll traces diverging from the two opposed margins. Secretory
cavities within cortex of both strobilar axis and sporophyll.
