Erdei, B.: The Sarmatian flora from Erdőbénye-Ligetmajor, NE Hungary

the climate must have been Mediterranean with hot and dry summer and mild winter. Mostly it can be compared with the climate of the east Mediterranean since those stereophyllous forests in which deciduous elements also exist can be found there. Floristically the two localities (Ligetmajor and Kővágó-oldal) are quite similar. In respect of the species of Quercus arose a question, that is to say why Quercus kubinyii (KOVÁTS et ETT.) BERGER replaces the stereophyllous species (Quercus mediterranea UNGER and Quercus urophylla UNGER) in Ligetmajor. Two kinds of explanation are conceivable: namely, the floras are not uniform in respect of their age and the other conception is that the ecological conditions were different. Another difference existing between the two floras is that Cystoseirites partschii STERNB. is totally missing in Ligetmajor. From this the conclusion can be drawn that in this region a freshwater inlet must have existed. On the other hand, the riparian elements form a less significant group in Ligetmajor than in Kővágó-oldal. This can presumably be attributed to differences in field conditions: namely, in Ligetmajor there must have existed a steeper slope than in Kővágó-oldal. Table 1.
