On the origin of the Oriental plane tree ( Platanus orientalis L.)
Abstract Oriental plane tree ( Platanus orientalis ) is native to the East Mediterranean region and sister to three western North American species, together forming the Pacific North American–European (PNA‐E) clade. Its sister clade, comprising several eastern North American–Mexican species, has bee...
