Summary BUSINSKY R. & KIRSCHNER J. 2006. Nomenclatural notes on the Pinus mugo complex in Central Europe. - Phyton (Horn, Austria) 46 (1): 129 - 139. - English with German summary. Selected names in the genus Pinus are analyzed. The neotype of the name P. undnata var. pseudopumilio WILLK. is replaced by a lectotype (PR). The name P. uli- ginosa NEUMANN in WIMM. is shown to be the correct donor of the epithet for the bog pine at the rank of subspecies and a new combination is proposed [P. undnata RAMOND ex DC. subsp. uliginosa (NEUMANN) BUSINSKY comb, nova]; the taxonomic conclusions are mainly based on the studies of Polish authors on this taxon. The name P. hartenbergiensis LIEBICH is analysed; a neotype is selected from the locus classicus population in W. Bohemia. The name is correct for the bog pine at the rank of species. The name P. rotundata LINK was published as early as 1827, its neotype is shown to be in full accordance with the protologue. A field study of the neotype po- pulation shows that the name does not represent a hybrid or intermediate between P. mugo and P. undnata, nor it can be used for the bog pine. It represents inter- mediates between P. undnata subsp. undnata and subsp. uliginosa, closer to the former taxon. The name P. obliqua REICHENB. was neotypified in conflict with the protologue; therefore, a new neotype is selected and the name again represents in- termediates between P. undnata subsp. undnata and subsp. uliginosa, closer to the former taxon. *) Ing.
