The glaucophytes, also known as glaucocystophytes or glaucocystids, are a small group of unicellular algae found in freshwater and moist terrestrial environments,[1][2] less common today than they were during the Proterozoic.[3] The stated number of species in the group varies from about 14 to 26.[4][5][6] Together with the red algae (Rhodophyta) and the green algae plus land plants (Viridiplantae or Chloroplastida), they form the Archaeplastida.
The glaucophytes are of interest to biologists studying the evolution of chloroplasts as they may be similar to the original algal type that led to the red algae and green plants, i.e. glaucophytes may be basal Archaeplastida.[1][7][4]
Unlike red and green algae, glaucophytes only have asexual reproduction.[8]
