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).
