Answer: Rhynia is one fossil pteridophyte.
Explanation:
Pteridophytes are the first vascular plants with xylem and phloem. These plants were well developed in the paleozoic era.
Rhynia is the only single species under the genus of Devonian vascular plants. Rhynia gwynne-vaughanii was the sporophyte generation of a vascular, axial, free-sporing diplohaplontic embryophytic land plant of the Early Devonian that had anatomical features more advanced than those of the bryophytes.
Rhynia has a creeping rhizome and has repeated dichotomous and adventitious branching. The rhizome axes are cylindrical in shape and naked and generally exhibit similar morphology and internal anatomy as compared to the aerial axes though they do not have stomata.
