Taxonomy and distribution of macrosciadium alatum (BIEB.) V. Tichomirov & Lavrova (Apiaceae): A new alien species in the flora of europe

Abstract

The paper presents the taxonomical position and the description of the characteristic features of Macroscia-dium alatum {=Ligustkum alatum). The species was recorded in the Western Bieszczady Mts (the northern part of the Carpathians) in July 2007 and is new to the flora of Europe. Its natural range comprises mainly the Caucasus region and the origin of M. alatum in south-east Poland is quite puzzling. The species has most likely been delibe-ratelly brought into the area. M. alatum spreads quite intensively. It penetrates semi-natural vegetation systems and seems to be expansive.
