Fruits are rounded nuts attached to a four-winged involucrum. The main three wings are triveined, the medial wing is longer, rounded at the apex, the very short forth wing envelopes the fruit basally. Venation consists of elongate fields along the main veins, forming smaller areoles towards the lobe margin (translated and emended from Knobloch 1958 ). D i s c u s s i o n. The fruits of Engelhardia occur only rarely in the Knížecí plant assemblage and match other occurrences in the European Tertiary (see Mai in Jähnichen et al. 1977 ).
