Record Type: concept
Progymnospermophyta (extinct division) (Plantae (kingdom), Eukaryota (domain), ... Living Organisms (hierarchy name))

 

Note: Clade of woody plants intermediate between ferns and gymnosperms comprising the Devonian genus Archaeopteris. Like the true gymnosperms, they commonly had secondary growth of their vascular tissues (i.e. they produced wood), and some grew to be tall trees. However, unlike true gymnosperms, they did not produce seeds, but rather released their spores as do ferns. Two major groups of progymnosperms are recognized, the Archaeopteridales and Aneurophytales. A third group, the Protopityales is sometimes recognized, but it is poorly known, and so its relationship to other plants is unclear.

Additional Notes:
Dutch ..... Clade van houtige planten die tussen die van varens en gymnospermen (naaktzadige planten) inzit en het genus Archaeopteris uit het Devoon omvat. Zoals bij de echte gymnospermen was er bij hen gewoonlijk sprake van secundaire groei van hun vaatweefsel (dat wil zeggen, ze produceerden hout) en sommige soorten waren grote bomen. In tegenstelling tot echte gymnospermen produceerden ze evenwel geen zaadjes maar sporen, net als varens. Men erkent twee grote groepen progymnospermen: de Archaeopteridales en Aneurophytales. Een derde groep, de Protopityales, worden soms erkend, maar is slecht bekend, waardoor de relatie met andere planten onduidelijk is.
