Givulescu (1979: 102
, pl.41, fig.14) assigned a leaflet from Late Miocene strata of Chiuzbaia (
Romania
), very similar to the material from Oriolo, to
Gleditsia allemanica
HEER, 1859
. According to
Givulescu (1979)
,
G
.
allemanica
was present in middle and Late Miocene floras of
Germany
,
Hungary
,
Romania
and
Ukraine
. Recently, well-preserved leaflets of
Gleditsia
have been reported from Late Miocene and Pliocene localities in
Poland
and
Germany
.
Worobiec and Worobiec (2019)
reported
Gleditsia europaea
G.
WOROBIEC, 2019
, from the Bełchatów Lignite Mine (
Poland
), which they considered most closely related to the modern North American species

aquatica
MARSHALL, 1785
. From the Pliocene of Frankfurt,
Kvaček et al. (2020)
reported
Gleditsia pliocaenica
KVAČEK, TEODORIDIS et DENK, 2019
, which they compared to the western Eurasian
G

caspica
. The Pliocene specimens are very similar to the material from Oriolo.

Leaflets of
Gleditsia
differ from the Neogene extinct genus
Podocarpium
(
Herendeen 1992
)
by their crenulate margin.
