ABSTRACT The components of the flagellar apparatuses of the male and female gametes of Derbesia tenuissima (De Not.) Crouan are compared with those in other swarmers of green algae. Both the male and female gametes were found to have a cruciate microtubular root system, a non‐striated capping plate which connects basal bodies, two electron dense terminal caps which partially cover the proximal end of the basal bodies, and two small system II fibrous roots. Similarities exist between these components and those suggested to be typical of ulvalean swarmers. Based upon these similarities, it is proposed that the Caulerpales be classified in the Ulvaphyceae rather than in the Charophyceae or Chlorophyceae.
