Scytophyllum waehneri (Stur) nov. comb., the correct name for Scytophyllum persicum

Evelyn Kustatscher, Christian Pott & Johanna H.A. van Konijnenburg-van Cittert

Scytophyllum is a Triassic seed fern genus to which currently more than 28 species distributed in Eurasia are attributed. Scytophyllum persicum is a characteristic taxon of the Late Triassic flora of Iran and adjacent countries. Discovery of part of the original collection of the conspecific Bernoullia waehneri from the same area and age made a revision of this species necessary that resulted in the proposal of the new combination Scytophyllum waehneri (Stur) nov. comb, since B. waehneri has priority over S. persicum. Scytophyllum waehneri differs from all other species in Scytophyllum in the smaller dimensions of the fronds and pinnae and the distinct secondary veins forming a sort of fishbone structure on the lamina.
