Species
Caytonia is an extinct genus of seed ferns.
Caytonia has berry-like cupules with numerous small seeds arrayed along axes [2]
Different organs attributed to the same original plant can be reconstructed from co-occurrence at the same locality and from similarities in the stomatal apparatus and other anatomical peculiarities of fossilized cuticles.
