Lamium confertum voor het eerst waargenomen in België, groeiend in de bermen van een recent gebouwde spoorwegbrug

A first record of Lamium confertum from Belgium, growing on road verges along a newly constructed railway bridge. – The first record of Lamium confertum from Belgium, in 2018, raises questions. The species is not difficult to identify with the help of keys in recent floras. Yet it is not clear why in Belgium it has gone unnoticed for so long: overlooked? really not present? Neither is it understood how it has arrived at the recently discovered location in Aalter (prov. Oost-Vlaanderen). The paper briefly presents possible introduction pathways and describes how L. confertum can be differentiated from related species
