Abstract
Nilsonia holyi Kvac˛ek et Knobloch, sp. nov. is described as a new entire-margined cycadophyte foliage species from the Cenomanian of the Bohemian Massif. It displays entire-margined lamina, a typical emarginate apex, simple secondary veins and a characteristic arrangement of stomata. N. holyi is compared with N. bohemica Velenovský, N. orientalis Heer, N. tenuinervis Seward, N. thomasii Harris and other entire-margined Nilsonia species. New occurrences of N. bohemica are reported from the localities Jetr˛ichovice and VelkéOpatovice. Width of leaf lamina is suggested as a good morphological character for Nilsonia bohemica leaf impressions.
