Abstract

An orchid population of Dactylorhiza traunsteineri in the southeastern part of the Czech Bohemian Forest (Šumava Mts) in southwestern Bohemia (near the village Želnava) was studied for more than 20 years. Besides the hybrid of this species with D. comosa subsp. majalis (= D. ×dufftiana), plants corresponding with the hybrid combination D. fuchsii × D. traunsteineri were observed. This new hybrid is described as Dactylorhiza ×silvae-gabretae Procházka et Čurn. Isozyme markers separated by nondenaturing discontinuous polyacrylamide gel electrophoresis were used for description and classification of plants belonging to D. traunsteineri, D. fuchsii and D. ×silvae-gabretae. The pattern of SDH (shikimate dehydrogenase) isozymes exhibited a hybrid character in analysed plants of D. ×silvae-gabretae.
