First report of Fallopia x bohemica in Romania

Fallopia x bohemica (Polygonaceae, EPPO List of Invasive Alien Plants) has been identified in more than 78 localities in Eastern Transylvania, Romania since the 2000s. F. x bohemica is found along the Tisa River, the Bistriţa River and its tributaries, as well as in the Moldavian plain. In these infested sites, F. x bohemica replaces the native vegetal communities over large areas. The species had initially been erroneously identified as Polygonum cuspidatum (= Fallopia japonica). As a consequence, many records relating to F. japonica may correspond to F. x bohemica. In Romania, F. x bohemica was either introduced from Central Europe as an ornamental plant and then escaped from gardens, or spread naturally from west to east along watercourses.
