Material.—A single fragmentary leaf MZ VII/33/28 from Krasnobród.

Description.—The preserved part is about 5 cm long and 2.2 cm wide; the total length cannot be estimated. Shape probably oblong, margin entire, primary venation pinnate with one basal vein and alternating eucamptodromous secondaries, their spacing possibly increasing apically. Poorly preserved intercostal tertiary veins percurrent, rarely spaced. A possible fragment of an intramarginal vein present.

Remarks.—This fragmentary leaf is compared to Eucalyptolaurus depreii Coiffard Gomez, Thiébaut, and Kvaček, 2009 from the uppermost Albian–lowermost Cenomianian of Charente−Maritime (western France; Coiffard et al. 2009) on account of an elongate shape, pinnate venation and presence of an intramarginal vein (it should be noted that this may also be a subjacent secondary asymptotically approaching the margin). Differences in our taxon include greater width to length ratio and gradual incurving of the secondary veins ( E. depreii has very elongate leaves and relatively short secondaries reaching the intramarginal vein). A somewhat speculative accommodation within Lauraceae may be suggested.

The second leaf included within the same taxon by Malicki et al. (1967) has straight, subopposite secondaries and no intramarginal vein. It is referred to here as Dicotylophyllum sp. 2 (see below).
