Lychnis /ˈlɪknɪs/ is a genus of 15-25 species of flowering plants in the family Caryophyllaceae, native to Europe, Asia and north Africa. The genus is closely related to (and sometimes included in) Silene, differing in the flowers having five styles (three in Silene), the seed capsule having five teeth (six in Silene), and in the sticky stems of Lychnis. Common names include "campion" (shared with Silene) and "catchfly", the latter name based on the sticky stems.
