Diagnostic characters: Trilete, laevigate spore; contour somewhat triangular with convex<br />
sides and rounded corners. Trilete laesurae straight, gaping, extending twothirds<br />
the distance to the periphery. Exine two-layered, 1 pm thick; endexine thin.<br />
Measurements: 55 X 43 pm in diameter.<br />
Stratigraphic range: <strong>Middle</strong> Europe (Late Oligocene-Pliocene), Southeast Asia<br />
(Eocene) and Japan (Miocene).<br />
Germany: Late Oligocene or ? Early Miocene (borehole Bernheide); Late<br />
Oligocene (St. Augustin and Upper Bavaria); Miocene (Tessin); Late <strong>Tertiary</strong><br />
(Neubrandenburg).<br />
Czechoslovakia: Oligo-Miocene (South Bohemia).<br />
Hungary: Miocene-Pliocene (Eger, F6t, Piispokhatvan, Papa, Litke,<br />
N6gnidszakcil, Szokolya, Hida, Als6vadcisz, Megyasz6).<br />
Japan: Miocene (Iki).<br />
Indonesia: Eocene (Yogyakarta-Java) .<br />
Remarks: The specimens belonging to Leiotriletes maxoides Kr. minoris Kr. differ<br />
from L. maxoides Kr. maximus (Pf.)<br />
form <strong>of</strong> the Y-mark and thickness <strong>of</strong> the exine.<br />
Botanical affinity: Schizaeaceae, Lygodium.<br />
Kr. and L. maxoides Kr. maxoides in size,<br />
