Tilia × haynaldiana Simonk. (T. platyphyllos Scop. × T. tomentosa Moench) in Northern Greece.

The article provides information on the occurrence of Tilia ×haynaldiana, a hybrid of T. platyphyllos and T. tomentosa, in Greece. This hybrid has been previously known to exist only in Northwest Romania and Montenegro. T. ×haynaldiana combines two characteristic features of its parental species: the ribbed fruits of T. platyphyllos and the stellate indumentum of T. tomentosa. Probably, such hybrids are more common than reported earlier but often are not distinguished from their parental species. [ABSTRACT FROM AUTHOR]
