Types

Original diagnosis/description

Leaf interpreted as trifoliolate (Fig. 15D); terminal leaflet ovate, base cuneate; margin serrate, teeth rarely spaced; venation palmately pinnate, palinactinodro- mous; midvein stout, two basal veins emerging from leaf base, secondary veins forming chevron pattern by intercon- nected secondary veins between adjacent primaries in the lower part of the lamina. Presumed lateral leaflets unlobed with pinnate venation.

Etymology

In honour of Gustav Williger (1856–1937; for biographic notes see Springer 1914: 114–117, Anonymous 1937), in recognition of his contribution to the study of the Cretaceous of Lower Silesia (Williger 1882).

Stratigraphy

Cretaceous, Upper Cretaceous, Santonian
Czerna Formation, most probably lower or middle Santonian.

Locality

Czech Republic
Probably Luisenhain, temporary excavations in the first half of the 20th century. In the collection the type material is labelled “Bunzlau”, but due to recent mislabelling of some specimens (see Appendix 1, entry on Luisenhain) it is unfortunately impossible to be certain about the original locality.
