VARIABILITY OF NAVICULA MUTICOPSIS VAN HEURCK (PENNATAE DIATOM)

The author investigated the variation of Navicula muticopsis van Heurck on 365 microphotographs which were collected by HIROSHI FUKUSHIMA (Assistant Professor of Botany, Yokohama Municipal University) from the East Ongul Island (in the Antarctic) on the Feb. 3, 1959. Comparatively, there are distinc...

In all varieties and forma one typical character is noticed (Navicula muticopsis van Heurck var. gausii Heiden and Kolbe forma semicruciata form), that is, the striae on one side is absent in the central part of schale, hence Navicula muticopsis van Heurck var. gausii Heiden and Kolbe forma semicruciata Heiden and Kolbe which is known for this important character should be considered a synonym of this variety.
