Lamium
''Lamium'' (dead-nettles) is a genus of about 30 species of flowering plants in the family Lamiaceae, of which it is the type genus. They are all herbaceous plants native to Eurasia and northern Africa, with several widely naturalised across much of the temperate world. Description The genus includes both annual and perennial species; they spread by both seeds and stems rooting as they grow along the ground. They have square stems and coarsely textured pairs of leaves, often with striking patterns or variegation. They produce double-lipped flowers in a wide range of colours. Taxonomy In volume 2 of ''Species Plantarum'' published in 1753, the Swedish botanist Carl Linnaeus established genus ''Lamium'' by recognizing four species: ''Lamium album'', ''Lamium purpureum'', ''Lamium amplexicaule'', and ''Lamium multifidum''. The name ''Lamium'' is the primary generic name in use today. , Plants of the World Online accepts the following species: * '' Lamium album'' L. – (w ...

Lamium Galeobdolon
''Lamiastrum galeobdolon'', the yellow archangel, is a species of flowering plant in the mint family Lamiaceae. It is native to Europe and western Asia but it is widely introduced in North America and elsewhere. It is the only species in the genus ''Lamiastrum'' with yellow flowers. Another common name for this species is golden dead-nettle. In New Zealand, it is called the aluminium plant or artillery plant. The common names archangel and dead-nettle have been in use for hundreds of years, dating back to at least the 16th century. ''Lamiastrum galeobdolon'' comprises four closely-related subspecies that are sometimes considered to be four separate species, one of which, the variegated yellow archangel (''Lamiastrum galeobdolon'' subsp. ''argentatum'') from central Europe, is widely present as an invasive subspecies in several European countries outside of its native range and also in New Zealand, Canada, and the United States.

Lamium Bifidum
''Lamium bifidum'' is a species of flowering plant in the mint family Lamiaceae, native to the Southern Europe. It was first described by botanist Domenico Cirillo in 1788. Description ''Lamium bifidum'' is an annual herbaceous plant. It possesses an erect or decumbent stem, white flowers and a deeply bifid lower lip. Flowers form in verticillasters of 20 or more flowers. These flowers are sometimes cleistogamous. An analysis of the essential oil of ''Lamium bifidum'' bracts and leaves identified the highest constituents as germacrene D (34.9%), β-caryophyllene (11.5%) and α-Humulene (6.8%). This contrasted with the primary constituents identified in the flowers: myrcene (47.2%), β-caryophyllene (11.8%) and sabinene (11.0%). The species possesses a chromosome count of 2n = 18. Taxonomy Domenic Cirillo first described ''Lamium bifidum'' in his ''Plantarum Rariorum Regni Neapolitani'', published in 1788. John Isaac Briquet's 1897 taxonomy placed the species within t ...
