Note Distribution of oak species in the Czech Republic J Kobli&jadnr;ek Department of Forest Botany and Phytocenology, Faculty of Forestry, University of Agriculture, Zem&jadnr;d&jadnr;lskà 3, 613 00 Brno, Czech Republic Summary — Only 4 native species of oaks were known in Czechoslovakia until 1974, namely Quer- cus cerris, Q petraea, Q pubescens and Q robur. In that year, Magic published a paper in which he quoted another 5 oak species from Slovakia. During my study in the Czech Republic, I have found, in addition to the above mentioned species, Quercus dalechampii, Q polycarpa, Q virgiliana and very rarely Q frainetto but not Q pedunculiflora. The newly discovered oak species are concentrated particularly in southern and southwestern Moravia. Quercus dalechampii / Quercus polycarpa / Quercus virgiliana Résumé — Répartition des chênes en République tchèque. Quatre espèces de chênes ont été reconnues en Tchécoslovaquie jusqu’en 1974: Quercus cerris, Q petraea, Q pubescens et Q robur. La même année, Magic publia un article dans lequel il mentionna 5 espèces supplémentaires en Slovaquie. Au cours de mon étude, j’ai reconnu d’autres espèces en république tchèque, en plus de celles déjà évoquées. Il s’agit de Quercus dalechampii, Q polycarpa, Q virgiliana, et plus rarement Q frainetto. Q pedunculiflora n’a pas été rencontré. Ces espèces récemment découvertes sont con- centrées dans la partie sud et sud-ouest de la Moravie.
