Myagrum perfoliatum

1. Myagrum perfoliatum L. (S-Eur., SW-As.) – A rather rare and much decreasing, always ephemeral alien. First recorded in 1821 in Leuven (without further details). Observed as a wool alien in the Vesdre valley between 1891 and 1907 (possibly persisting for some time on a talus slope). Furthermore recorded on various occasions and in widely scattered locations but much rarer since 1950: on waste land near a steel plant in 1954 in Hoboken, on a railway bank in Vilvoorde, also in 1954 and on a dry pond margin in Nismes in 1956. In the past decades observed several times as a grain alien: in a roadverge in Pittem in 1994 (Verloove & Vandenberghe 1995) and under a grain conveyor at the Kattendijkdok in the port of Antwerpen in 1998. Since 2011 Myagrum perfoliatum was also regularly seen with several individuals in the port-area of Gent. Finally, in 2015 also recorded near a small grain mill in Moen.
Myagrum perfoliatum is usually found on waste land but there are several old records from agricultural fields as well (beets, etc.).
