Streptophyta (/strɛpˈtɒfɪtə, ˈstrɛptoʊfaɪtə/), informally the streptophytes (/ˈstrɛptəfaɪts/, from the Greek strepto 'twisted', for the morphology of the sperm of some members), is a clade of plants. The composition of the clade varies considerably between authors, but the definition employed here includes land plants and all green algae except the Chlorophyta and the more basal Prasinodermophyta.[4]

Classifications
The composition of Streptophyta and similar groups (Streptophytina, Charophyta) varies in each classification.[5][citation needed] Some authors include only the Charales and Embryophyta (e.g., Streptophyta[1][6], Streptophytina Lewis & McCourt 2004)[3], others include more groups (e.g., Charophyta Lewis & McCourt 2004[3]; Karol et al. 2009[citation needed]; Adl et al. 2012[6], Streptophyta[7]; de Reviers 2002; Leliaert et al. 2012, Streptobionta Kenrick & Crane 1997[citation needed]; some authors use this broader definition, but exclude the Embryophyta, e.g., Charophyta[8] Leliaert et al. 2012[citation needed], Charophyceae Mattox & Stewart, 1984[citation needed], Streptophycophytes de Reviers, 2002[citation needed]).
The clade Streptophyta includes both unicellular and multicellular organisms. Streptophyta contains the freshwater charophyte green algae and all land plants that reproduce sexually by conjugation. Mesostigma viride, a unicellular green flagellate alga may be a basal Streptophyte.[9][10]
These earlier classifications have not taken into account that the Coleochaetophyceae and the Zygnemophyceae appear to have emerged in the Charophyceae + Embryophyta clade, resulting in the synonymy of the Phragmoplastophyta and Streptophytina/Streptophyta sensu stricto (a.k.a. Adl 2012[6]) nomenclature.[11]
