Streptophytina

From Wikipedia, the free encyclopedia

Streptophytina

Scientific classification
Kingdom: Plantae
(unranked) Streptophytina

Streptophytina is formally a subdivision or subphylum (but sometimes used at the division level, where more appropriate would be the use of the term Streptophyta, see below) which contains two classes: Charophyceae, containing the Charales order (Charophytes sensu stricto); and Embryophyceae, which contains the embryophytes (land plants, bryophytes, and vascular plants).

The term streptophyta, formally a term for a division or phylum, is also used to indicate a subkingdom and used to include land plants (embryophytes) as well as several orders of green algae (class Charophyceae) previously included in the division Charophyta.[1]
