Biology:Mesostigma
Mesostigma is a genus of unicellular biflagellate freshwater green algae, with a single species Mesostigma viride, covered by an outer layer of basket‐like scales instead of a cell wall.[1][2] It is the only known genus in the class Mesostigmatophyceae[3] (and thus, the only genus in the family Mesostigmataceae[4] and the order Mesostigmatales[5]).
Earlier studies were unable to resolve the position of the species, and it was often placed as a sister to all other green algae, as one of the basal members of the Streptophyta, close to Chaetosphaeridium.[6][7][8] More recent studies agree that Mesostigma and Chlorokybus form a clade, being the earliest diverging of the green plants, specifically within Charophytes.[9][10][11][12]
