Discussion | Subspecies 3 (3 in the flora). 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.

Of conservation concern. Silene ovata is a very distinctive species with large, ovate, acuminate, sessile, paired leaves, and very narrowly lobed white petals. The flowers open at night and are moth-pollinated. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
