Abstract

Cymbella janischii (A. W. F. Schmidt) De Toni and Gomphoneis minuta (Stone) Kociolek & Stoermer collected from the upper Tama River in Oume City, Tokyo, were examined with a scanning electron microscope (SEM). We present 56 pictures here which were taken from various directions as a basis for future research in taxonomy or morphology.
