I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.
What we do. Every page goes through several hundred of perfecting techniques; in live mode. Quite the same Wikipedia. Just better.

Streptophyta, informally the streptophytes (from the Greek strepto, for twisted, i.e., the morphology of the sperm of some members), is an unranked clade of plants. The composition of the clade varies considerably between authors. One common definition is the Charophyta, including the land plants, the embryophytes (bryophytes and vascular plants)[2][3] The Phragmoplastophyt Zygnematophyceae are considered to be the sister of the land plants.[4][5][6]

Classifications

The composition of the Streptophyta and similar groups (Streptophytina, Charophyta) varies in each classification.[7][citation needed] Some authors are more restrictive, including only the Charales and Embryophyta (e.g., Streptophyta Jeffrey 1967; Adl et al. 2012, Streptophytina Lewis & McCourt 2004), others include more groups (e.g., Charophyta Lewis & McCourt 2004; Karol et al. 2009; Adl et al. 2012, Streptophyta Bremer, 1985; de Reviers 2002; Leliaert et al. 2012, Streptobionta Kenrick & Crane 1997; some authors use this broader definition, but exclude the Embryophyta, e.g., Charophyta Cavalier-Smith 1993;[8] Leliaert et al. 2012, Charophyceae Mattox & Stewart, 1984, Streptophycophytes de Reviers, 2002).

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 senso stricto (a.k.a. Adl 2012) nomenclature.[9]
