Fossil charophytes and hydrophytic angiosperms as indicators of lacustrine trophic change. A case study in the Miocene of Catalonia (Spain)
L'interet des macrophytes aquatiques fossiles pour the determination des contextes trophiques anciens est etudie dans le lac Miocene de La Cerdanya mais a change vers une situation plus oligotrophique andaline.
The predominantly aquatic flora from Pellendorf, Lower Austria, Late Miocene, Pannonian - a systematic study
The presented results here are fundamental for the palaeoecological interpretation of the whole sedimentary sequence at Pel- lendorf.
Schenkiella genus novum, thorny disseminules of unknown affinities from the Lower Miocene of central Europe
A new fossil genus Schenkiella Wojcicki & Z. nov. is installed to accommodate thorny/horny disseminules called "Trapa" credneri Schenk, an index fossil for the middle Early Miocene Floral Assemblage ("Florenkomplex") Bilina - Brandis sensu Mai of central Europe.
Variability, hybridization and distribution of Prunus fruticosa [Rosaceae] in the Czech Republic and Slovakia
Recently discovered collections extend the geographical range of the smut fungus Sphacelotheca polygoni-serrulati to Cameroon and Zambia.
The smut fungus Sphacelotheca polygoni-serrulati Maire is newly reported from Cameroon on Persicaria decipiens (R. Br.) K. L. Wilson and from Zambia on P. pulchra (Blume) Sojak. Persicaria pulchra is…
A new species ofTrapa (Trapaceae) from the Pliocene of the Zennern Depression, near Fritzlar (Hesse, Germany)
A single, unusual, but highly informative specimen of TrapaLinné 1753 from Pliocene sediments collected in a gravel-pit within the Zennern Depression, near Fritzlar (Hesse, Germany), has been subjected to detailed investigation and suggests that the two genera are closer than previously recognised and have evolved from a shared common ancestor.
