GBS datasets of western Eurasian lime trees (Tilia) and the Hyrcanian Forest taxa. null

Morphological uniformity in Tilia (Malvaceae s.l., Tilioideae) and unclear species delimitations resulted in over 500 names associated with the about 30 species of this genus. This is also an issue for the Hyrcanian Forest diversity hotspot of northern Iran, where between one and seven Tilia species were described to occur. We used genotyping-by-sequencing (GBS) to analyze the phylogeny of western Eurasian Tilia species, place the Hyrcanian Tilia populations, and infer their phylogeography.
