The Charophyta are a division of green algae, including the closest relatives of the embryophyte plants. Because they exclude the embryophytes, they make a paraphyletic group (though they are occasionally restricted to simply the Charales or stoneworts, which are monophyletic). Characteristically, flagellate cells do not occur in this division. Divisions Chlorophyta Charophyta Streptophytina (Subdivision) The green algae are the large group of algae from which the embryophytes (higher plants) emerged. ... The embryophytes are the most familiar group of plants, including trees, flowers, ferns, mosses, and various others. ... Paraphyletic - Wikipedia /**/ @import /skins-1. ...

Charophyta are commonly known as stoneworts or brittleworts.
It was commonly believed that Charophyta were related to embryophytes (land plants).
Some of the characteristics between Charophyta and land plants are: homologous chloroplasts, as welll as similarites in mitosis, sperm ultrastructure, cell wall composition, peroxisomes, and genetic data.
