Rhynia belongs to the class psilophytopsida of the division psilophyta. This class includes all the extinct members of the division. This group has a single order psilophytales. The psilophytales include the simplest extinct vascular plants, which were discovered in the fossil form among the rocks of the early devonian period of the palaeozoic age. Rhynia in fossil form was discovered by Kidston and Lang (1917) from the place Rhynie in Aberdenshire in Scotland. This plant was not found in present age; it is extinct and found only in the form of petrified fossils. There are evidences that rhynia genus possessed two species, Rhynia gwynne-vaughani and R. major.
