Among the spp. of Lychnis and Silene in N.Z., only S. dioica and S. latifolia are dioecious. These 2 spp. can be distinguished from each other by fl. colour (pink to red in S. dioica, white in S. latifolia) and posture of capsule teeth (revolute in S. dioica, erect to patent in S. latifolia). S. dioica and S. latifolia have 5 styles in ♀ fls, in common with Lychnis spp. in which, however, the fls are always ⚥.
This sp. has been known as Lychnis dioica, S. diurna, and Melandrium rubrum in N.Z.
