Abstract

In 2018, a new species, Heracleum ponticum (Lipsky) Schischk., was identified in the Priozersky district of Leningrad oblast. The H. ponticum plant does not contain photodynamically active furocumarins, but interspecific hybrids of this species with the H. sosnowskyi Manden. plant may contain some substances in their juice that are dangerous to human skin. The approximate growing area of H. ponticum is almost 0.7 ha.
