Palynology of Middle Tertiary lacustrine deposits

Palynology of Middle Tertiary lacustrine deposits 265
Derivation of name: semi Oat.) = half; undulosus Oat.) = having a wavy form.
Remarks: The new specimens with their faint undulated sculpture are quite similar to
mmipollenites undulosus Wolff from the Pliocene of Dettingen a. M., although their
exine is even more delicately sculptured.
Botanical affinity: Ulmaceae, Ulmus.
Genus Carpinuspollis Takahashi 1979.
Type species: Carpinuspollis carpinoides (Pflug 1953) Takahashi 1979.
Carpinuspollis sp.
PI. 17, figs. 17 - 18.
Description: Pentaporate pollen with rounded-polygonal contour and straight or convex
sides. Exine two-layered, chagrenate,
1 -1.5 /lm thick. Five circular pores,
without labra, atria or annuli; one or two pores may be located subequatorially.
Measurements: 24 - 29 /lm in equatorial diameter.
Remarks: The genus Carpinip£tes was established by Srivastava (1966) on the type
species Carpinipites ancipites (Wodehouse) Srivastava. This genus is defined as a
triporate or tetraporate pollen comparable to those of Carpinus. Afterwards, the
genus Carpinuspollis was introduced by Takahashi (I979) on type species Carpinuspollis
carpinoides (Pflug) Takahashi, notwithstanding, Nagy (I985) indicated
Carpinus pollen with three to six pores from the Hungarian Neogene as Carpinipites
carpinoides (Pflug, 1953) n. c.
Botanical affinity: Betulaceae.
Infraurma Periporiti Van der Hammen 1956 emend. Potonie 1960.
Genus Multiporopollenites Pflug 1953 emend. Potonie 1960.
Type species: Multiporopollenites maculosus (R. Potonie 1931) Thomson & Pflug
1953.
? Multiporopollenites sp.
PI. 17, figs. 23a-b.
Description: Polyperiporate pollen of rounded rectangular outline. Exine threelayered,
finely rugulate, 1.8 /lm thick; ectexine intrarugulate; endexine smooth;
ectexine as thick as endexine. Seven pores rather randomly situated, 4.5-5.5 /lm
in diameter; annuli weakly developed, 1 - 1. 5 /lm wide; without labrum and
atrium.
Measurements: 34 X 32 /lm in diameter.
