124 samples originating from a depth range of 23.5 -1779.1 m of the Iharosberény-I borehole were processed. 26 taxa were separated, complemented bv several unidentified twig and stem remains and root prints. 19 samples were studied from the Tiszapalkonya-I borehole, recovered from the depth of 1460.0 - 1969.9 m. Apart from the 16 taxa identified, further stem fragments and root prints were observed. Most of the floristical remains are leaf prints. A print of a fruit was found in the Tk-I borehole. The state of preservation of the leaves is generally good, in some cases excellent. Unfortunately, the size of the drilling core often prevented us from collecting the otherwise well preserved leaves in complete size. The material of the two boreholes is treated separately below.

Material: sample No 234, depth 302.9-302.8 m One basal and one medial fragment of a pinna. The width of the basal fragment is 2.1 cm, that of the medial one is 2.2 cm. The basis is asymmetrical, the venation is dense. The midvein is stout, the margin of the pinnae is finely serrate. The species was widely distributed in Europe throughout the Miocene. It is considered an accessory element of humid floras. It occurs in post-Sarmatian, i.e. Pannonian beds, in the herbaceous layer of the Gfyptostrobus europaeus forests of western Hungary.
