fragments discussed here are too small to define the exact arrangement and position of stomata. Gymnospermae gen. et sp. indet. (Figs 6-7) Material: BP 99.500.1. Description: The cuticle is of medium thickness and constructed of isodiametric cells the length and width of which are 16.3-33.8 urn and 15-25 urn, respectively. Anticlinal walls are straight, uniformly thickened and sometimes weakly rounded. The construction of the one and only stoma (and the remains of two others at the margin of the cuticle) which is much bigger than the epidermal cells proves its gymnospermous affinities. Presumably, the arrangement of stomata is parallel with the longitudinal axis of epidermal cells. Type of stomata must have been cyclocytic with 6 subsidiary cells surrounding the 50 urn long stomatal pore. Subsidiaries are smaller than epidermal cells. Unfortunately, guard cells have fallen out during fossilization or preparation.

Material: BP 99.501.1. Description: A thin cuticle with isodiametric cells. Anticlinal cell walls are hardly to be seen, but epidermal cells seem to be pentagonal or hexagonal and the weakly thickened cell walls are presumably undulating. The arrangement of the heavily compressed stomata is random. The length and width of a relatively better preserved stoma is 25 urn and 22.5 urn, respectively. Stoma type appears to be anomocytic (however, in fact it is paracytic, see in KVACEK 1979). There are numerous, considerably thickened, round shaped formations to be recognised on the cuticle which represent simple hair bases (modified hair base cells are not observable). Unfortunately, there is no hair remained. A secretory body together with the Studio hoi. hung. 30-31, 1999-2000
