Pteridophyta (division) (Plantae (kingdom), Eukaryota (domain), ... Living Organisms (hierarchy name)) |

Note: A large group of around 20,000 species of flowerless, seedless vascular plants having true roots from a rhizome and fronds that uncurl upward, reproducing by spores. The ferns are an ancient lineage of plants, dating back to at least the Devonian; during the Palaeozoic, tree-ferns grew several meters tall. The ferns include three living groups (Marattiales, Ophioglossales, and leptosporangiate ferns) and two or more extinct groups. An additional group, the Psilotales, is tentatively included in the ferns, although the group is vastly different from living ferns and its relationships are uncertain. The ferns group is also referred to as Polypodiophyta or Polypodiopsida when classified as a subdivision of tracheophyta (vascular plants).

Additional Notes: |
|
| Chinese (traditional) ..... 約有兩萬個左右物種的龐大類群，為無花、無子的維束管植物，有根莖形成之真正的根，和向上展開的葉體，透過孢子繁殖。蕨類是古老的植物祖先，至少可追朔到泥盆紀時期；在古生代期間，樹蕨可長到數公尺高。 蕨類包含三個現存類群（觀音座蓮目、瓶爾小草目與薄囊蕨類）以及兩個或以上的滅絕類群。另一個類群是松葉蕨目，雖然其與現存蕨類大不相同且關係也不明確，目前暫時歸類於蕨類中。當蕨類被歸類為導管植物門（維束管植物）下時，又被稱作真蕨門或真蕨綱。 |
