Autochthonous diatom flora in Fujimae Tidal Flat, a river-mouth tidal flat in central Honshu, Japan, is displayed as a checklist with microphotographs. We evaluated the diatom flora using the combination of three preparation methods; a nuclear staining method by hematoxylin solution, a sieving method, and a hydrogen peroxide cleaning method. In total 82 diatom taxa were regarded as components of the autochthonous diatom flora. Among them, 52 taxa detected by the nuclear staining method must have been alive on the tidal flat sediments mainly as an epipelon or a sedimented plankton. Sixty eight taxa detected from sieved samples with the relative frequency of >0.5% were putatively living there mainly as an epipsammon.
