Types

Original diagnosis/description

Fronds bipartite with an acute-angled bifurcation, pinnate. Pinnae alternate to subopposite, entire-margined, lanceolate to narrow-elliptic with the widest part within the lower third; pinna base contracted and basally decurrent; pinna apex obtuse. Venation faint; basal group of veins arising from the rachis at an acute angle, dichotomizing repeatedly at very acute angles to form an even, almost parallel dense venation throughout the remaining lamina. Stomata superficial or only slightly sunken, with differentiated, evenly cutinized lateral subsidiary cells.

Etymology

The specific epithet is chosen in honour of Prof. Dr. Klaus Bandel (Hamburg, Germany) for his contributions to our knowledge of the geology and palaeontology of Jordan.
