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 pseudatocion is occasionally grown in gardens and rarely occurs as a weed in California. It is similar to another garden escape, S. pendula, but it differs in having a calyx tube with a very long, slender base and unlobed petals.
