Erdei, Boglárka; Lesiak, Maria: A study of dispersed cuticles, fossil seeds and cones from Sarmatian (Upper Miocene) deposits of Sopron-Piusz puszta (W Hungary)
arranged stomata are 15-17.5 um and 7.5-15 urn, respectively. Outer stomatal ledges are thickened. Discussion: It was described from Miocene brown coal deposits (Wackersdorf) by PETERS (1963). It was assigned with a question mark to Helobiae. However, JÄHNICHEN (manuscript) identified it as the cuticle of the exocarp of Ocotea rhenana Menzel and, moreover, he did not exclude the possible affinity with the recent Ocotea foetens Benth. et Hook. (Canary Islands). Dicotylophyllum sp. 1 (Fig. 25) Material: BP 99.509.1. Description: The cuticle is of medium thickness with 15-25 urn long and 10-18.8 um wide isodiametric cells. Their arrangement is pentagonal and hexagonal. Anticlinal cell walls are straight and the surface of the cuticle is wrinkled. Stomata are randomly orientated. Length and width of stomata are 15-27.5 urn and 18.8-22.5 um, respectively. Stomatal pores are closed and very narrow with a length of about 10 um. The type of the subsidiary cells around the guard cells cannot be accurately defined. Discussion: The wrinkled surface of the cuticle recalls the cuticle of Illipophyllum thomsoni Kräusel et Wey land (KRÄUSEL and WEYLAND 1959, Taf. 28, Fig. 71 ; Taf. 29, Figs 72-75), assigned to the family Sapotaceae. Dicotylophyllum sp. indet. (Fig. 26) Material: BP 99.510.1. Description: The cuticle is thin with isodiametric cells arranged hexagonally and polygonally. Anticlinal cell walls are thin and weakly undulate. Cuticle is poorly preserved and stomata may have fallen out during fossilization or preparation. Discussion: The structure of the cuticle recalls the family Lauraceae.
