et al., p. 16, pl. 8, fi gs 18, 19.
R e m a r k s. These pollen grains represent
arctotertiary element (A). They occur in fossil
palynofl oras since the Oligocene, more frequently
in the Neogene, and commonly in the
Pliocene (Stuchlik et al. 2009). Pollen grains
of this taxon were encountered in all studied
profi les, mainly in the grey clay horizon and
Henryk seam, in quantities not exceeding 1%.
Today Corylus genus (about 15–19 species
of tall shrubs and trees) occurs in northern
temperate zone of Europe, America and Asia
(Krüssmann 1976, Kubitzki 1993).

R e m a r k s. Pollen grains of Betula type occur
in Europe since the Palaeocene ( Krutzsch
1970d, Muller 1981). Trivestibulopollenites
betuloides occurs in the Eocene to Pliocene
deposits, and represents arctotertiary (A) element
(Ziembińska-Tworzydło et al. 1994a,
Stuchlik et al. 2009). Pollen grains of T. betuloides
were regularly noted in all analysed
profi les in quantities of a few per cent (max.
10–12% in the Mużaków series and Lusatian
seam).
The recent species of Betula genus (about
60) are distributed in temperate and boreal
zones of the northern hemisphere (Krüssmann
1976). They are photophilous plants, but they
have little requirements about soil (Bugała
1991).

R e m a r k s. These pollen grains resemble
recent pollen of Myrica gale L. They occur in
the Eocene to Pliocene, and represent arctotertiary
(A) element. In Poland they are reported
from the Upper Oligocene to Miocene deposits
(Stuchlik et al. 2009). They were regularly
encountered in the studied material.

1969 Myricipites rurensis (Pfl ug & Thomson) n. comb.,
Nagy, p. 245, pl. 53, fi g. 27.
R e m a r k s. These pollen grains represent subtropical/arctotertiary
(P2/A) element, and occur
in Poland in the Eocene to Miocene deposits
(Stuchlik et al. 2009). Kohlman-Adamska
(1993) compares this species with Myrica nagy
Thunb. and M. salicifolia Hochst. ex Rich. Pollen
grains of Triatriopollenites rurensis were
regularly encountered in the studied material.
They were more frequent in the Lusatian seam.
The oldest pollen grains of Myrica type
are known from the Cretaceous (Santonian)
of USA. In Europe they are more frequent
since the Eocene and Oligocene (Muller 1981).
Nowadays this genus (with about 35 species
of evergreen or deciduous trees and shrubs) is
distributed in temperate and subtropical zones
of both hemispheres. Myrica adenophora grows
in China, M. carolinensis in North America,
M. nagy in north-western Himalayas, M. rubra
in Asia, M. salicifolia in Ethiopia (Krüssmann
1977). M. gale occurs on sea-shores of northern
and western Europe in maritime climate zone
and in northern part of North America. Morella
