According to Knobloch (1958, translated from Czech) the involucres are asymmetric, not divided into lobes, on one side entire, on the opposite coarsely dentate with double denticulate larger teeth, venation palmate, including up to 7 basal primary veins, thicker stretching to the teeth, thinner veinlets ending before margin at about 2/3 of the involucre, higher order veins perpendicular or slightly oblique.

D i s c u s s i o n. Similar involucres and fruits have been found at Seifhennersdorf associated with foliage of C. grandis ( Walther and Kvaček 2007) . At Knížecí they occur quite often and clearly prevail over Carpinus cordataeformis .
