Cytotaxonomic study of some taxa of the subtribe Orchidinae (Orchidoideae, Orchidaceae) from the Iberian Peninsula

Abstract

Chromosome numbers in 29 populations belonging to 21 species of Orchidinae from the Iberian Peninsula have been counted. For four Iberian endemic species, Anacamptis coriophora subsp. carpetana, Dactylorhiza caramulensis, Orchis tenera, and Serapias perez-chiscanoi, the number of chromosomes is reported here for the first time. For another three, Anacamptis champagneuxii, Himantoglossum hircinum, and Orchis langei, this number has been established in Iberian representatives. Moreover, new ploidy levels have been obtained for Anacamptis champagneuxii and Dactylorhiza sambucina. Some taxonomic, phylogenetic, and phytogeographic comments are made for several species or groups of species from the Western Mediterranean region.
