The recent discovery of Artemisia campestris L. subsp. maritima Arcang. (syn. A. crithmifolia L.) in Britain raises questions over its native status, with possibly significant consequences for the conservation agencies. This review finds difficulties, however, in the biogeographic and ecological arguments for native status, and better evidence for non-native status in the molecular genetic data. These arguments carry different weight but, on balance, A. campestris subsp. maritima seems more likely to have arrived relatively recently in Britain, by anthropogenic means, and is therefore best understood as a neophyte.
