M a t e r i a l. Oriolo MSF 646, 664, 665, 666.

D e s c r i p t i o n. Leaf, palmate, petiolate, petiole up to 50 mm, distal part widened, lamina 5-lobed, 45–53 mm long, 50–62 mm wide, lobes oblong to rhombic, with few – usually one on each side of lobe – coarse, blunt teeth in upper part.

R e m a r k s. The fossil-taxon A. subcampestre occurred in Central Europe at around the Middle Miocene (StröbitzerHermann and Kovar-Eder 2002), and was a typical accessory element of riparian and mesophytic forest during the middle and Late Miocene. In analogy with the ecology of the modern A. campestre, Güner et al. (2017) suggested that the fossilspecies could also have been part from drier, more open sites, in addition to riparian and mesophytic lowland forests. Adamovic (1909) mentions A. campestre as an element of Šibljak vegetation in the Balkans.
