Epidermal patterns so far encountered in Cenomanian plants of the Bohemian Massif suggest the presence of the following more or less natural independent lineages: Platanus-Credneria group (stomata laterocytic, associated fructifications Platanus-like), "Aralla"-Debeya group (stomata laterocytic to anomocytic), Myriophyllum group (stomata paracytic with the sunken guard cells, fructifications aggregate), Cocculophyllum group (stomata paracytic, partly with subdivided subsidiary cells, mesophyllous secretory bodies) and "Diospyros" group (stomata cyclocytic). Except Platanus-Credneria lineage no modern counterparts have been found for the studied early angiosperms.

Key words: Cenomanian, leaf anatomy, angiosperms.
