SCHMEISSNERIA-MICROSTACHYS (PRESL, 1833) KIRCHNER-ET-VANKONIJNENBURG-VANCITTERT, COMB-NOV AND KARKENIA-HAUPTMANNII KIRCHNER-ET-VANKONIJNENBURG-VANCITTERT, SP-NOV, PLANTS WITH GINKGOALEAN AFFINITIES FROM THE LIASSIC OF GERMANY

The female fructification belonging to the new genus Schmeissneria, Schmeissneria mia ostnchys (Presl, 1833) Kirchner et Van Konijnenburg-Van Cittert, comb. nov., has been found attached to short shoots bearing leaves that were formerly called Glossophyllum? sp. A. Weber, 1968 and that are consequently now also called Schmeissneria microstachys. The male fructification Stachyopitys preslii Schenk, 1867 belongs in all probability to the same plant. Furthermore, the female fructification Karkenia hauptmannii, Kirchner et Van Konijnenburg-Van Cittert, sp. nov. has been found attached to short shoots carrying leaves that have been called Sphenobaiera a spectabilis (Nathorst) Florin but are now removed from this species and are consequently also called Karkenia hauptmannii.
