In his 1973 article, Skvortsov called "the true brittle willow, S. fragilis" the willow that had come unnoticed to Europe from Asia Minor with human migrations, hybridized with the native white willow, and inflicted the mess. For the next 35 years botanists remained undecided about the solution of the surfaced problem. Finally, it was decided that the name "brittle willow" should remain with the hybrid, so that botanists in each European country did not have to rewrite their field guides and floras. The previously overlooked parent species from Asia Minor was described only in 2009 and received the name "S. euxina"--from "Póntos Éuxenos," Hospitable Sea, the Ancient Greek name of the Black Sea. That's how it happened that we now have to scribe an "x" in front of the Latin name of brittle willow.
