OCCURRENCE. — Ashikajima Fm. DESCRIPTION Trilete microspore. Amb rounded triangular with convex sides.The laesurae are raised, slightly undulating, and extend to the 3/4 of the spore radius. Exine cicatricose. On the proximal face, a small and psilate contact area is followed by 3 sets of about 9 narrow muri (about 0.5 µm wide, separated by furrows of the same width) parallel to the equator.On the distal face, many narrow muri are more or less parallel to one set of the proximal face,and they go from one to another top of the spore ( Fig. 11 ). The ornamentation of this form corresponds to the typeVI-B defined by Krutzsch (1963) . Equatorial diameter = 40-45 µm . BOTANICAL AFFINITIES Schizaeales , Anemiaceae .
