Leaflets oval, very fragmentary, on the apex bluntly acute, on margin irregularly bluntly coarsely serrate, midrib straight, distinct, secondary veins bent, craspedodromous, accompanied by single intersecondaries, not reaching the margin, tertiary veins oblique. Resin ducts have been recorded in the mesophyll during maceration. Epidermal structure not preserved except distinct and dense wavy cuticle striation.

D i s c u s s i o n. Fragmentary specimens clearly correspond with the more complete material from Bechlejovice, Kundratice and other sites of North Bohemia and Saxony, from where this well recognizable accessory element has been reported ( Kvaček and Walther 1998, 2004). For nomenclatural details see Kovar-Eder et al. (2004).
