Non-vascular Plants
No xylem and phloem (no roots/stems/leaves), gametophyte is dominant in alternation of generations life cycle, sporophyte generation dependant on gametophyte, water is needed for reproduction, dispersal of species by spores.
Hepaticophyta
The liverworts. Example: Marchantia. 10,000 species.
Bryophyta
The mosses. 12,000 species of mosses.
Vascular Plants
Have xylem and phloem (have roots/stems/leaves), sporophyte generation is dominant in alternation of generations life cycle.
Seedless Vascular Plants
In addition to vascular plant attributes: water needed for reproduction, gametophyte is independent, do not produce seeds, dispersal of species by spores.
Psilotophyta
Whisk ferns. Example: Psilotum nudum.
Lycophyta
Club Mosses. 1,000 species. Example: Lycopodium, Isoetes, Selaginella.
Equisetophyta
Horsetails. 155 species. Examples: equisetum.
Polypodiophyta
Ferns. 12,000 species. Examples: all ferns.
