Charophyceae , containing theCharales order (Charophyte s "sensu stricto"); andEmbryophyceae , which contains theembryophyte s (land plants ,bryophytes , andvascular 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 divisionCharophyta . [ [http://tolweb.org/Green_plants/2382 Green plants ] ]References
