There are four divisions of plant life that make up the class of seedless , vascular plants . Those industrial plant naval division are Psilophyta , Lycophyta , Sphenophyta and the Pterophyta , agree to the Horticulture and Crop section at Ohio State University . Vascular plant have systems of tubes used to transport water through the plant life . This chemical group of vascular flora does not multiply with seeds ; instead , they regurgitate with spores .
Club Mosses
gild mosses , often called creeping cedar or terra firma true pine , are small creeping plants that are establish in the tropical flock expanse . They are a perennial evergreen industrial plant with forked branch and musical scale - same leaves . night club mosses reproduce with spores that arise on their alter leave . This group of vascular plant was very thickly settled during the carboniferous period , or the period in metre that contribute to most of the coal sediment , about 360 million to 299 million years ago , according to the Horticulture and Crop Science department at Ohio State University . They once grew to the size of trees , but are now low - lying plant .
Psilotum
Psilotum is also known as the whisk broom fern . These plants miss folio and roots , which make them the simplest of vascular plant . The whisk fern is mostly find in tropic and subtropical region of Asia and the Pacific , where they produce in cracks and crevices in the sandy grease near beach . They are native to swamplands and opt rich , moist soil , but can digest a sure degree of drouth .
Horsetails
Horsetails are often referred to as bread and butter dodo because the plant has changed piddling for an estimated 100 million years . The mature plants resemble horse tails . This group of industrial plant is also call scouring rushes and candock . The stems of the horsetail plants carry abrasive and are often dried and used in Japan to finish woodcraft . They put up a smoother final airfoil than emery paper .
Ferns
There are about 20,000 different species of fern . It is the most vulgar of all seedless , vascular plant . fern prefer moist , shadowy , woodland areas , but they are adaptable to a extensive variety of environment including remote raft , rocky cliff , and tropic forest beds , and they can be found next to bodies of water or in open field . The leaves of the fern are squall fronds and arise by unroll to mold large leaves . Some ferns are used as food for thought , such as the fiddlehead , but most ferns in the United States are used as landscape plant life . aboriginal Americans reportedly used ferns to make patch and would itch the frond of the fern on an open cold shoulder , grant to the Arkansas State Park system . Ferns have antiseptic property that can forestall small cut from becoming infected .
