et al., p. 22, pl. 13, fi gs 8–10a, b.
R e m a r k s. This morphological species occurs
in the Palaeocene to Miocene deposits, and
represents tropical (P1) element (Ziembińska-
Tworzydło 1998). Pollen grains of this type
of structure are presently excluded from the
collective morphological genus Tricolporopollenites
due to their similarity to pollen of Cornaceae,
particularly to the subfamily Mastixioideae
(Ziembińska-Tworzydło et al. 1994b). In
the studied material pollen grains of Cornaceaepollis
satzveyensis were found mainly in
the Lusatian seam, in quantities not exceeding
1%.
Today subfamily Mastixioideae with one
genus – Mastixia Bl. (25 species of evergreen
trees) occurs in the Indo-Malayan region in
temperate zone (Heywood 1978).

1960 Araliaceoipollenites edmundi (Potonié); Potonié,
p. 97.
R e m a r k s. This taxon occurs in Europe
in the Oligocene to Lower Pliocene deposits,
and represents subtropical (P2) element
(Ziembińska-Tworzydło 1996). It used to be
compared with Cornus alba, C. brachypoda, C.
sanguinea and C. stolonifera (Mamczar 1962).
Nevertheless, pollen grains of A. edmundi have
reticulate surface related to family Araliaceae.
Kohlman-Adamska (1993) compares them with
the recent species Acanthopanax sciadophylloides
Franch & Sav. (from Japan) as well as
Panax L. – P. pinnatum and P. pentadactylon
(from south-eastern Asia) from the Araliaceae
family. In the studied material pollen grains of
Araliaceoipollenites edmundi were encountered
regularly. In the Lusatian seam they occurred
in quantities a few per cent (max. 8%).

R e m a r k s. These pollen grains occur in
Europe in the Oligocene and Miocene deposits,
and represent subtropical (P2) element
(Ziembińska-Tworzydło 1996). They are similar
to pollen of the recent Aralia chinensis L.
(Kohlman-Adamska 1993) from mesophytic
forests of south-eastern China. Pollen grains of
Araliaceoipollenites euphorii were encountered
in all studied profi les in small quantities, usually
in samples with A. edmundi. Similarly
these species were observed together by Mamczar
(1962).

R e m a r k s. These pollen grains represent subtropical
(P2) element (Ziembińska-Tworzydło
et al. 1994a). They occur in the Miocene and
Pliocene deposits (Oszast 1960, Stachurska
et al. 1973, Thiele-Pfeiffer 1980, Muller 1981).
In the examined material several pollen
grains of this type of structure were found,
in samples with Araliaceoipollenites edmundi
and A. euphorii.
Nowadays the family Araliaceae contains
herbs, shrubs, trees and climbers occurring
mainly in warm-temperate zone of North
America and tropical South America and Asia
(Hutchinson 1973). The genus Aralia (about
