Microreticulatisporites sp. 1 ( Fig. 8M, P View FIG )
OCCURRENCE. — Kimigahama Fm (one specimen).
DESCRIPTION Microspore. Amb circular. The laesurae are not seen. Exine microreticulated and finely scabrate. The mesh is polygonal, of various shapes and sizes (lumina 0.2 to 1.5 µm in diameter). The exine is 2 µm thick. Equatorial diameter = 40-45 µm.
BOTANICAL AFFINITIES
The ornamentation of this species shows similarities with that of some Polypodiales (Dennstaedtiaceae) figured by Tryon & Lugardon (1991). Moreover, the genus may have sphenophyte affinities, e.g. with the Noeggerathiales ( Knox 1950; Singh 1964).
