Mesostigma is a species of freshwater green algae which is one of the most basal of the green algae, branching from the others near the point of the split between the Streptophyta and the Chlorophyta.[1]
The exact relationships of Mesostigma have not been clear, however. Open questions have included whether it is sister to all other green algae or whether it is one of the more basal members of the Streptophyta,[2][3] and what other algae, if any, are related to it. Some authors have proposed that Mesostigma is close to Chaetosphaeridium,[4] but others have found that Mesostigma is more closely related to Chlorokybus than to Chaetosphaeridium or Chara (Chara and Chaetosphaeridium are described at Charales).[1][5]
