⚠️ Taxonomic note:
Kew accepts Lamium maculatum (L.) L. and places Lamium truncatum Boiss. in its synonymy. The morphology, flowering period, habitat and historical regional localities above are taken specifically from Mouterde’s account of L. truncatum, rather than inferred from other Lamium species. Kew lists Lebanon-Syria within the native range.
