In 2016 a single, large population of Melampyrum pratense (Orobanchaceae) was discovered in Vaglaskógur forest in NE Iceland. This is very peculiar as the closest population of this myrmecochorous, slowly dispersing, hemiparasitic species is known from the Shetland Islands located ca. 1000 km south-east from Vaglaskógur. We undertook research aimed to elucidate whether the species is a recent anthropogenic addition to the Icelandic flora or its presence should be attributed to a natural long-distance dispersal event.
The origin, possible local dispersal scenarios and the time of residence of the species will be discussed in the light of ecological research.
