Description:
Mariopteridaceae
seed ferns (Pteridosperms) group contains two genera, Marioptris and Karinopteris.
Mariopteris
is a form genus for relatively small compact fronds which are bifurcated twice.
The pinnules are tongue-shaped to assymmetrically triangular in outline with a distinct basal lobe (at least the pinnules closest to the main axes). Although it is clear that most mariopterids are seed ferns, their natural affinity remains unclear. Karinopterids obviously had a climbing growth habit. This species, like other Karinopteroids and Mariopteroids, had a vine- to liana-like growth habit and climbed with specialized climber hooks.
