Pinnularia and Myriophyllites (FIG. nodosa observed here are from streams, ponds and small lakes in the Rocky Mountains and Sierra Nevada Mountains of the western United States. Their walls are composed of two halves called If one observes the surface of the water immediately after swirling up the diatoms, one regularly finds Pinnularia, which float on the surface of the water. ) Krammer in this paper.
