Charophyceae is a class (biology) of charophyte green algae. Some botanists include Charophyceae and chlorophyte green algae in the plant kingdom. [2] Charophyceae are a class within the Streptophyta.[3][4][5] Current consensus treats Charophyceae as a class under division Charophyta, with Chlorophyta remaining a distinct division.[6]

Many of the complex traits related to sexual reproduction, photosynthesis, and other defining characteristics of plants evolved first in Streptophytes; analysis of cpDNA (chloroplast DNA), for instance, reveals that many characteristics of plant chloroplasts evolved first in the Streptophyte genera Staurastrum and Zygnema.[2][7]
