R e m a r k s. This taxon occurs in Europe in the
Middle Miocene deposits, e.g. in central Poland
(Stuchlik et al. 2001). In the studied material
these spores were found sporadically.

R e m a r k s. This taxon is known in Europe
from the Eocene to Pliocene deposits; in Poland
occurs sporadically in the Middle Miocene
(Doktorowicz-Hrebnicka 1960, Stuchlik et al.
2001). These spores were rare in the analysed
material.

R e m a r k s. This species occurs in Europe in
15
the Palaeocene to Pliocene deposits, and it
is common all over Poland in the Lower and
Middle Miocene (Stuchlik et al. 2001). In the
studied material these spores were often found,
but they were not numerous.

R e m a r k s. This species occurs in Europe in
the Eocene to Pliocene deposits. In Poland
it is common in the Miocene and rare in the
Pliocene (Stuchlik et al. 2001). In the studied
material these spores were encountered
regularly in small quantities, mainly in the
Lusatian seam.

R e m a r k s. This species occurs in Europe in
the Middle Miocene to Pliocene fossil palynofl
oras. It is also known from the Middle and
Upper Miocene deposits from central Poland
(Stuchlik et al. 2001). In the studied material
these spores were found sporadically. In addition,
some other not closely determined Sphagnaceae
spores were found.
All fossil spores related to the recent genus
Sphagnum (Distancoraesporis, Distverrusporis
and Stereisporites) represent cosmopolitan
(P/A) climatic element (Stuchlik et al. 2001). In
Neogene deposits spores of Sphagnum usually
do not exceed 2–5%. In the studied material,
