Sapindaceae (Aceroideae) from the late Miocene flora of Sośnica near Wrocław – a revision of Göppert’s original materials and a study of more recent collections

Summary: ABSTRACT: The results of a revision and new studies of macroscopic plant remains of Acer (Sapindaceae s.l., including Aceraceae) from the late Miocene (= Pannonian) flora of Sośnica near Wrocław are presented. The following leaf species of the genus Acer L. occur in this flora: A.vindobonense (Ettingshausen) Berger, A. subcampestre Göppert, A. tricuspidatum Bronn, A. integrilobum Weber sensu Walther, and A. aegopodifolium (Göppert) Bajkovskaja ex Iljinskaja. For three of the species an emended diagnosis is given. The leaf species have been described on the basis of morphological analysis; the epidermis was preserved and investigated only for A. tricuspidatum Bronn. These fossil leaf species are accompanied by the fruits of the fossil taxa A. campestrianum Dorofeev and Acer sp. div.
