Discussion | Silene scaposa is a very distinct species with its subscapose inflorescence, coronalike ring of short petals, and distended fruiting calyx in which the veins to the lobes are markedly broadened and lanceolate. Variation in lobing of the corolla has been the basis for recognizing two varieties: var. scaposa (var. typica C. L. Hitchcock & Maguire), which has two-lobed petals, and var. lobata, which has four-lobed petals. However, these differences appear to be of little significance.

Silene regia is a very distinct, spectacular species with tall stems, a narrow, many-flowered inflorescence, and bright red petals. It is probably related to S. laciniata via S. subciliata. Silene regia is in the Center for Plant Conservation’s National Collection of Endangered Plants. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
