The species of Lamiaceae described in 1753 by Linnaeus as Phlomis zeylanica L. (= Leucas zeylanica (L.) R.Br.) and Phlomis indica L. (= Leucas indica (L.) R.Br.) are distinct. The neotype designated for Phlomis indica L. belongs to a different taxon, hence a specimen from the Linnaean Herbarium (LINN) is redesignated as neotype. Leucas lavandulifolia Sm. is the legitimate name for the Linnaean species Leonurus indicus L. The south Indian endemic variety Leucas lavandulifolia var. decipiens (Hook.f.) Chandrab. & S.R.Sriniv. is neotypified. A key to the four taxa is provided.
