Pl. 5, Fig. 21
M a t e r i a l. Pollen grains of?
Cunninghamioideae
occur in all the analysed samples, usually in high quantity.
R e m a r k s. Formerly,
Cunninghamioideae
were included in
Taxodiaceae
, e.g.,
Page (1990)
. After a taxonomic reassessment (
Gadek et al. 2000
,
Farjon 2005
),
Cunninghamioideae
and
Taxodioideae
are considered subfamilies of
Cupressaceae
.Pollen of
Cunninghamia
SCHREB.
has been reported, e.g., from the Middle Miocene deposits of Lavanttal (
Austria
;
GrÃmsson and Zetter 2011
), from Neogene deposits of
Georgia
(Transcaucasia) (
Shatilova et al. 2018
). Macroremains have been described from the late Oligocene to Pliocene of Central Europe (
Kovar 1982
,
Walther 1989
,
1999
,
Mai and Walther 1991
), as well as from the Middle and Late Miocene of
Romania
(
Givulescu 1975
). Light microscope studies of
Cunninghamia
pollen morphology were carried out by
Jimbo (1933)
,
Wodehouse (1935)
,
Erdtman (1943
,
1957
),
Ueno (1951)
,
Van Campo-Duplan (1951)
; recently,
Bouchal and Denk (2020)
extensively described the pollen morphology of
C
.
lanceolata
(LAMB.) HOOK.
under both the optical microscope and SEM. The abundant pollen grains from Govone do not show diagnostic features under the light microscope, despite having a morphology quite comparable to
Cunninghamioideae
. For an unquestionable attribution to this taxon, a SEM morphological study would be necessary, as recommended by
Bouchal and Denk (2020)
.
