Ozenda, So<5/ and against /GlavaS 1968 and 1974 in Horvát, GlavaS and Ellenberg/ the syntaxonomical concept of the Illyrian beechwoods. In an interesting way, not the correctness of my s'yntaxonomic views were most heavily debated but the fact, that my monographic work preceded and made needless other similar works. Horvát,GlavaS and Ellenberg literally rejected my syntaxonomic concept, in their book /1974/» but did not offer any alternatives and in fact they accepted its main points. GlavaS criticized also some new association names introduced by me. According to the later elaborated Phytosociological Code /Barkman, Moravec and Rauschert 1978/ all these criticized names turned to be legitime and valid ones. Therefore in the part II the theoretical basis of my phytosociological concept is reiterated emphasized and some final remarks on the mentioned discussion are pointed out. The examinations performed and the methods applied are discussed in a separate chapter. The phytosociological and forest »typological units were established based on d&ia from 200 permanent quadrats /Dauerquadrat/. Both field work and data analysis were carried out according to the methods of- the Zurich— montpellire phytosociological school /Braun-Blanquet 1928, 1951, SoS 1930, Zólyomi 1951/« In critical cases, when it seemed necessary, exact data evaluation was attempted through the use of statistical methods /Jaccard» 1928, Ellenberg 1954, Sorensen 1950, Looman and Campbell I960, Précsényi 1962/. The classification of the Illyrian beechwood associations by'PCA and cluster methods /Orlóci, 1966, Podani 1981/ was carried out by. Borhidi, Podani and Török /1982, in press/. Soil analyses and microclimate studies were carried out in. order to determine the acological conditions of each site. The soil analyses were done using appropriate methods developed at the Instiute of Pedology and Agrochemistry and In the Institute of Forestry Science. Information on microclimatic conditions was obtained throuh some ^000 observations coming from two 32-hours long measurements in 11 forest types. The regularities existing between the distribution of topography, ecological sites', phytosociological units and forest types were cleared up in the course of a phytosociological a foresttypological mapping of a forest area of 11 square kms. To acqire a knowledge of the quality and output of each forest typeforest assessment and timber volume measuring were carried out following Z. Fekete /1951, 1956/. With a view to the correcht valuation of different stands and to determine the right way of interference archival researche including studies of land registers, working plans of forestries, old maps were done. Major points made ia this book are: .It Zselic, together with the other regions of southern Transdanubia, belongs to the phytogeographic sector Praeillyricum within the Illyricum flora province. However its exact phytogeographlcal status is questionable, because its flora is intermediate between the flora of the Inner Somogy and that of Mecsek flora district. Therefore, the only way to determine the unambiguous phytogeographlcal status of Zselic is to make statistical comparisons between the two neighbouring flora districts. Investigations of this revealed that a/ Zselic can by no means be considered a separate flora district - as it was .suggested by A.O.Horváth /1974/; b/ its flora is more similar to that of Inner Somogy than to the Mecsek flora; ' c/ leaving out of the comparisons widespread species, the flora of Zselic 141
