Diatoms from the upper stream of the Yoshino-river, near the village Ikadaba were examined with an optical microscope. Ikadaba is situated at 34°14' N. L. and 136°04' E. on the northern mountain slope, about 500m above the sea level, of Mt. Odai. Diatoms grown on the stone-surface in the stream were collected in June 1965, in February 1966 and in April 1968. In each time stones on which the diatoms were grown were picked up from the central part of the stream as well as near the river side, and the diatoms were harvested from the stones.
Forty two species (including four varieties) belonging to sixteen genera were identified. Photographs and descriptions of these species are included in this paper.
