It is one of two genera in the family Psilotaceae, the other being Tmesipteris. An incredible variety of seedless plants populates the terrestrial landscape. Ferns are considered the most advanced seedless vascular plants and display characteristics commonly observed in seed plants. Pterophyta - includes ferns, whisk ferns, scouring rush gymnosperms - most contain seeds within cones heterosporous - microspores produced in male cones, megaspores created in female cones in sexual reproduction of pine. gnetophytes. The single genus Equisetum is the survivor of a large group of plants, known as Arthrophyta, which produced large trees and entire swamp forests in the Carboniferous. The stems and vascular systems of seed ferns had certain ultrastructural features similar to those of cycads, a small group of gymnosperms currently found in tropical and subtropical regions. Most of the 470-million-year history of plants on land belongs to bryophytes, pteridophytes and gymnosperms, which eventually yielded to the ecological dominance by angiosperms 90 Myr ago1,2,3.
