Taxonomy

Illecebrum verticillatum was first described by Carl Linnaeus in his 1753 Species Plantarum. It has sometimes been placed in a family of its own, Illecebraceae, but is usually placed in the family Caryophyllaceae.<ref name="Wilson"/> The genus name Illecebrum derives from the Latin word Template:Lang, meaning "enticement", although it is unclear how the name came to be applied to a plant such as I. verticillatum.<ref name="Wilson"/> The specific epithet Template:Lang means "whorled",<ref>Template:Cite book</ref> in reference to the arrangement of the flowers. The plant is sometimes referred to in published works as whorled knotweed or coral necklace, although it is unclear if these purported common names are actually used in practice.<ref name="Wilson">Template:Cite journal</ref>
