Palynology of Middle Tertiary lacustrine deposits

196 K. TAKAHASHI & U. lux
Late Oligocene (St. Augustin); Miocene (Machendorf, Welzow);
Pliocene (Berga, Gorsbach, Wallensen).
Belgium: Early Eocene (Epinois, Loksbergen).
Hungary: Early Eocene (Northern Bakony: Zire; southern Bakony: Urkut); Middle
Eocene (Northern Bakony: Dudar, Balinka; Mor Graben: Mor; southern
Bakony: Halimba); Late Eocene (Southern Bakony: Halimba); Early
Oligocene (Northern Bakony: Dudar; Mor Graben: Fehervarcsurgo); Middle
Miocene (Alsovadasz, Szokolya).
Poland: Miocene (Central Poland); Pliocene (Warsaw).
Remarks: Nagy (1985) pointed out that Krutzsch (1967) too readily used Mamczar's
misprinted name nutidus on the table (Tab. I, Fig. 9) disregarding his text.
Botanical affinity: Polypodiaceae.
Laevigatosporites nitidus (Mamczar) Krutzsch crassicoides Krutzsch
Pl. 4, fig. 2.
1967 Laevigatosporites nutidus crassicoides Kr., Atlas, Lfg. IV & V, p. 150, Taf. 53, Fig.
13-15.
Diagnostic characters: Monolete spore. In equatorial view outline bean-shaped with a
dehiscence furrow along the concave side. Exospore smooth, translucent, twolayered,
3 flm thick; at the dehiscence area the exine is thicker (ca. 5 flm thick).
Dehiscence furrow relatively long.
Measurements: 56 flm long and 39 flm wide.
Widthllength ratio: 0.696.
Stratigraphic range: Miocene in Middle Europe.
Germany: Early Miocene (Kasekow).
Remarks: Compared with Laevigatosporites nitidus (Mamczar) Kr. nitidus and L.
haardti (Pot. & Ven.) Th. & Pf. crassicus Kr., the Nigerian specimen differs either
in the thickness of the exospore or in the larger size.
Botanical affinity: Polypodiaceae.
