Papillaephyllum, a new genus of angiosperm foliage from the Cenomanian of the Czech Republic
Original language description
Angiosperm foliage Papillaephyllum labutae Čepičková et J. Kvaček, gen. et sp. nov. is described from the Cenomanian, Late Cretaceous of the Peruc-Korycany Formation in the Bohemian Cretaceous Basin, Czech Republic. Papillaephyllum labutae has been erected for rarely-found fossils with basal-angiosperm signs, characterized by serrate, sometimes double-serrate margins with rounded chloranthoid teeth, each bearing a papilla. Venation is semicraspedodromous to festooned-semicraspedodromous with reticulate tertiary venation. Its micromorphology is distinctive in having the entire abaxial cuticle covered by papillae. Papillae of the subsidiary cells often form as visible wreaths around the stomata. Stomata are latero-cyclocytic and stephanocytic-bicyclic.Well-pronounced and numerous papillae of the external epidermal surface are an indicator of possible fresh-water stress, identifying the taxon as possibly meso- to xerophytic. Based on macro- and micromorphological comparison with fossil and recent material, affinity of Papillaephyllum labutae with the family Chloranthaceae is highly probable.
