Sagenopteris phillipsii has narrow, palmately arranged leaves with anastomosing venation

Whole plant reconstructions[]

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.

  • Sagenopteris phillipsii may have been produced by the same plant as Caytonia nathorstii (ovulate organs) and (pollen organs).
