1962a Toroisporis (Toroisporis)? pliocaenicus (Thiergart)
n. comb., Krutzsch, p. 86, pl. 36, fi gs 1–9.
R e m a r k s. Spores of this taxon are intermediate
between Leiotriletes and Toroisporis
(Krutzsch 1962a), and are slightly similar in
structure to those of the recent Cyathaceae
and Lygodiaceae. They represent palaeotropical
(P) element and occur in Europe in the
Lower Miocene to Pliocene. They were reported
from the Lower – Middle Miocene deposits of
north-western Poland (Stuchlik et al. 2001).
Only one spore of this taxon was found in the
Mużaków series.

R e m a r k s. These pollen grains are similar to
pollen of the recent Cupressaceae, especially
to species Cupressus arizonica Greene., distributed
in the mountains in western part of North
America. They represent warm-temperate (A1)
element, and are common in the Lower and
Middle Miocene palynofl oras (Stuchlik et al.
2002).

R e m a r k s. Pollen grains resembling pollen of
the recent families Taxodiaceae, Cupressaceae
and Taxaceae (e.g. genera Cupressus L., Thuja
L., and Taxus L.). In Europe they occur in the
Palaeocene to Pliocene deposits, and represent
warm-temperate (A1) element (Ziembińska-
Tworzydło 1996). In Poland this taxon is
common in the Miocene deposits (Stuchlik
et al. 2002). These pollen grains were often
encountered in the analysed material.
The former family Cupressaceae contains 19
genera of trees and shrubs. The recent species
of Cupressus (about 15–20) grow in tropical
and subtropical zones of the eastern Mediterranean
Region to the Himalayas, in southern
China and southern North America. Taxaceae
contains 5 genera and about 20 species of trees
and shrubs extended mainly in East Asia. Species
of Taxus occur in the northern hemisphere
(Krüssmann 1972).

R e m a r k s. Pollen grains similar to pollen of
the recent Taxodium and Glyptostrobus, representing
warm-temperate (A1) element, occurring
in the Middle Eocene to Upper Miocene
deposits, in Poland are common in the Miocene
(Ziembińska-Tworzydło 1996, Stuchlik et al.
2002). These pollen grains were very often
encountered in all analysed profi les.
