1974 Sciadopityspollenites varius Krutzsch; Ziembińska-Tworzydło,
p. 356, pl. 13, fi g. 3.
R e m a r k s. This taxon occurs in central
Europe in the Oligocene to Middle Miocene
deposits (Stuchlik et al. 2002). These pollen
grains were sporadically encountered in the
analysed material.

1971 Sciadopityspollenites verticillatiformis (Zauer)
n. comb., Krutzsch, p. 178, pl. 54, fi gs 7–24.
R e m a r k s. This taxon occurs in central
Europe in the Eocene to Upper Miocene deposits
(Krutzsch 1971), in Poland is known from
the Lower and Middle Miocene (Stuchlik et al.
2002). These pollen grains were encountered
sporadically in the studied material.
Nowadays the genus Sciadopitys contains
only one species (S. verticillata Sieb. & Zucc.)
– tall evergreen tree growing in Japan (Hondo,
Sikoku) in the mountains up to 1700 m a.s.l.
in mixed forests with Chamaecyparis obtusa,
Ch. pisifera, Tsuga sieboldii, Pinus densifl ora,
Abies fi rma, Torrea nucifera, Magnolia obovata,
and Cercidiphyllum japonicum (Krüssmann
1972, Bugała 1991). Detailed studies of
recent pollen grains of Sciadopitys verticillata
revealed their huge variety (Kvavadze 1988),
what suggests that variability of Sciadopityspollenites
morphological genus could be result
of intraspecifi c variability.

1971 Sequoiapollenites major n. sp., Krutzsch, p. 220,
pl. 72, fi gs 1–24.
R e m a r k s. Pollen grains of this species occur
in the Lower Oligocene to Pliocene, and are
rarely found in the Middle Miocene deposits
all over Poland (Stuchlik et al. 2002). They
were sporadically encountered in the analysed
material.

1937 Sequoia - pollenites polyformosus n. sp., Thiergart,
p. 301, pl. 23, fi gs 6–11.
R e m a r k s. Pollen grains of this species are
common in the Lower Miocene to Pliocene
deposits all over Poland (Stuchlik et al. 2002).
At Legnica and Ruja they were often found,
usually in quantities of a few per cent.

1971 Sequoiapollenites rotundus n. sp., Krutzsch,
p. 222, pl. 73, fi gs 1–24.
R e m a r k s. A regularly circular shape is the
main feature of this morphological species,
occuring in the Middle Miocene to Pliocene
deposits. In the Polish Miocene pollen grains of
this species are found regularly (Stuchlik et al.
2002). At Legnica they were encountered sporadically,
mainly in the Lusatian seam.

1971 Sequoiapollenites rugulus n. sp., Krutzsch,
p. 218, pl. 71, fi gs 1–36.
R e m a r k s. Pollen grains of this species occur
in the Middle Oligocene to Pliocene deposits.
In the Polish Middle and Upper Miocene they
are found sporadically (Stuchlik et al. 2002). At
Legnica these pollen grains were encountered
mainly in the Lusatian seam.
