Overview
Taxonomy
The Infraphylum Moniliformopses is a member of the Subphylum Euphyllophytina. Here is the complete "parentage" of Moniliformopses:
- Domain: Eukaryota
- eukaryotes
- Kingdom: Plantae
Haeckel, 1866
- Subkingdom: Viridaeplantae
Cavalier-Smith, 1981 - Green Plants
- Phylum: Tracheophyta
Sinnott, 1935 Ex Cavalier-Smith, 1998 - Vascular Plants
- Subphylum: Euphyllophytina
- Infraphylum: Moniliformopses Kenrick & Crane, 1997, Nom. Nud. - Monilophytes
- Subphylum: Euphyllophytina
- Phylum: Tracheophyta
Sinnott, 1935 Ex Cavalier-Smith, 1998 - Vascular Plants
- Subkingdom: Viridaeplantae
Cavalier-Smith, 1981 - Green Plants
- Kingdom: Plantae
Haeckel, 1866
The Infraphylum Moniliformopses is further organized into finer groupings including:
- Class (4): Equisetopsida · Marattiopsida · Polypodiopsida · Psilotopsida
Classes
Equisetopsida
Equisetopsida, or Sphenopsida, is a of plants with a fossil record going back to the Devonian. Living species are commonly known as horsetails and typically grow in wet areas, with needle-like leaves radiating at regular intervals from a single vertical stem. Equisetopsida is placed in the botanical division of ferns (Pteridophyta), though sometimes regarded as a separate division Equisetophyta (also as Sphenophyta or Arthrophyta). [more]
Marattiopsida
Polypodiopsida
The Pteridopsida is a class of in the Division Pteridophyta that includes all the leptosporangiate ferns. In the recent 2006 classification by Smith et al. the class is renamed Polypodiopsida. This recent reclassification of Monilophyte (ferns) is based on multiple molecular studies published since 1994 that have clarified some of the confusion of the placement and relations among fern families. Polypodiopsida is one of four classes of Monilophytes (an Infradivision, this rank is not recognized by the International Code of Botanical Nomenclature), the other three being Marattiopsida, Equisetopsida, and Psilotopsida.

Psilotopsida
Psilotopsida is a class of -like plants. As circumscribed by Smith et al. (2006) it contains two families, Psilotaceae and Ophioglossaceae, placed in orders Psilotales and Ophioglossales, respectively. The affinities of these two groups have long been unclear and a close relationship between them has only recently been confirmed through molecular systematic studies. Psilotopsida is the sister-group to all other ferns (including Marattiaceae and Equisetaceae). [more]
At least 143 species and subspecies belong to the Class Psilotopsida.
