Phylogeny of diploid Cardamine in central Europe
The Iberian, Apennine, and Balkan Peninsulas harbour numerous narrowly distributed mostly high mountain polyploids species (specifically, Cardamine raphanifolia, C. gallaecica, C. dubia, C. silana, and C. amporitana). Despite earlier efforts, the diploid and potentially lower-level polyploid progenitors involved in the origin of these high-altitude species have not yet been identified.
