Silene uralensis is a very variable species complex. Recently, A. Kurtto (2001) has resurrected S. wahlbergella as a species distinct from S. uralensis, differing in its shorter petals and larger capsule. It appears to be confined to Scandanavia and adjoining arctic Russia. North American reports of S. wahlbergella (and its synonym Lychnis apetala) are all referable to S. uralensis.
