Members of the group contain ferns, horsetails, quillworts, clubmosses, and spikemosses. These plants used to be known as pteridophytes, but this turned out to become an inaccurate team mainly because ferns and horsetails tend to be more carefully linked to seed plants than to quillworts, clubmosses, and spikemosses. Seedless vascular plants flourished throughout the Devonian interval and in Carboniferous forests.
Some parasitic plants have misplaced the need to photosynthesize. Plants which include these don’t comprise chlorophyll and so are as a result not green.
