Streptophytes
The Streptophytes are a clade of plants that include all the true (land) plants, as well as the closest living green algae. This group is defined by two apomorphies: the dissolution of the nuclear membrane during mitosis, and the presence of paired flagella (when flagella are present at all) directed perpendicularly to each other
