Abstract

Senecio cambrensis is a new allopolyploid species, which originated independently in North Wales and in Edinburgh, Scotland. Despite extensive searches, the species has not been found growing at any of its previously recorded sites in Edinburgh or at other potential sites in the area since 1993. We have concluded that the Edinburgh lineage of S. cambrensis is now extinct and discuss possible causes of its extinction. The lineage was present in Edinburgh from at least 1974 and therefore survived in the wild for a minimum of 19 years. The species remains well established in parts of North Wales.
