PLATE 8, FIGURE 72

This species belongs in the Attenuatae section of Gomont (Monogr. p. 224) and is closely akin in form to Oscillatoria longearticulata Hansg. and narrower than O. acuminata Gomont. It is to be distinguished by its relatively long cells with conspicuously clear centers free from granules. It is larger in diameter than 0. longearticulata and narrower than O. acuminata.
