L e c t o t y p e: BP 55.2477.1 illustrated by Ettingshausen (1866, pl. 22, fig. 2 as Ficus daphnogenes ) – Kučlín, North Bohemia, Late Eocene) and reillustrated in Hably et al. (2001).

Leaves alternate, variable in lamina shape and size as well as in epidermal structure, simple, long petiolate, petiole 3–4 cm long, often pulvinate at the attachment to lamina and geniculate; lamina entire margined, hypostomatic, elongate to narrow ovate (length/width mostly more than 1.5), 4 to more than 6 cm long, 2.5–4 cm wide, symmetrical to moderately asymmetrical at the base, rounded, rarely truncate to subcordate, acute to acuminate at the apex, texture chartaceous to coriaceous, venation eucamptodromous, basally triveined, rarely with thin additional outer basal veins, midrib straight or slightly bent, lateral primaries thin, slightly bent, reaching rarely more than half, but usually one third of the lamina length or lower, secondaries irregularly alternate, arising at uneven distances of about 1–3 cm at an angle of 30–45°, bent, tertiaries percurrent or forked, dense, almost perpendicular to the secondaries, areoles mostly quadrangular without veinlets.

D i s c u s s i o n: The leaf anatomical characteristics given by Kvaček and Wilde (2010) are based on the material of Messel. The morphological variation of both populations of Messel and Kučlín does not differ in any respect.
