    Arenaria norvegica subsp. norvegica was re-discovered in Ireland in 2008 after an absence of 47 years. A detailed survey in 2009 revealed a small population restricted to skeletal soils on the edges of limestone pavement. A. norvegica subsp. anglica occurs in an almost identical habitat in Northern England. Irish plants also appear to flower at least a month earlier and produce more infloresences than in Britain. These differences warrant further investigation given the isolation of the Irish population. That it remained undetected for so long is remarkable and cautions against declaring a species as ‘extinct’ even in such a well botanized locality as the Burren.
