Silene ovata
Silene douglasii
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.

Varieties 3 (3 in the flora).
Silene douglasii is usually readily recognized by its characteristic short, retrorse, grayish-white, eglandular pubescence on the calyx and pedicels. This, together with the usual absence of lateral teeth on the petals, appears to be the only reliable character separating it from S. parryi. However, intermediates between the two species occur, and it is probable that the occasional plants of S. douglasii with stipitate-glandular hairs in the inflorescence (e.g., var. rupinae and some plants that have been referred to var. monantha) have arisen through gene exchange with S. parryi, although it should be noted that A. R. Kruckeberg (1961) reported that such hybrids, when artificially produced, were sterile.
