Monocotyledons from the Early Campanian (Cretaceous) of Grünbach, Lower Austria

Four monocotyledons, Araciphyllites austriacus sp. nov., Pandanites trinervis (Ettingshausen) comb. nov., Sabalites longirhachis (Unger) comb. nov. and one unclassified monocotyledon leaf type are described from the Campanian of Grünbach in Austria mostly on the basis of leaf morphology. A new speci...

More Information
Summary:Four monocotyledons, Araciphyllites austriacus sp. nov., Pandanites trinervis (Ettingshausen) comb. nov., Sabalites longirhachis (Unger) comb. nov. and one unclassified monocotyledon leaf type are described from the Campanian of Grünbach in Austria mostly on the basis of leaf morphology. A new species of Araciphyllites is described and compared to recent representatives of the family Araceae. An emended diagnosis of the genus Pandanites is proposed and species Pandanites trinervis is revised on the basis of the detailed morphology and anatomy of its leaves. The unique construction of leaves of the Pandanaceae is discussed and used for comparison with recent and fossil representatives of the family. Sabalites longirhachis is characterised by costapalmate leaves, which are not dissected into segments. Relationship to similar species of the genus Sabalites is discussed. A fragmentary preserved leaf of an unnamed monocotyledon is included to show the diversity of monocotyledons in the Grünbach Campanian wetlands.
