Leaflets asymmetrical, long petiolulate, lamina narrow falcate, 42–57 mm long and 9–15 mm wide, margin widely irregularly (?glandular) crenate, venation semicraspedodromous, midrib bent, secondaries irregularly spaced, almost perpendicular to the midrib, tertiaries very thin

D i s c u s s i o n: Rare leaflets are assignable to Ailanthus on the gross morphology and recall some Early Miocene Ailanthus foliage that accompany Ailanthus fruits at Parschlug ( Kovar-Eder et al. 2004) and elsewhere. The morphotype from the Late Eocene of Kučlín is morphologically quite variable as it is common in leaflets of compound leaves. The glands on the margin considered diagnostic of Ailanthus ( Corbet and Manchester 2004) are not quite distinctly preserved due to strong compression.
