*Lamium dissectum Withering. Cutleaf Dead-nettle. Phen: Apr-May. Hab: Lawns, fields, roadsides, disturbed areas. Dist: Native of Eurasia.

Origin/Endemic status: Eurasia

Taxonomy Comments: This taxon is apparently an allopolyploid derivative (2n=36), resulting from hybridization of L. purpureum and another species, perhaps L. amplexicaule. Because of its allopolyploid status, this taxon should not be treated as a variety of L. purpureum. It is, however, possible that some individuals identified here may be sterile hybrids (2n=18).

Synonymy : = Lamium hybridum Vill. – C, F, G, NY, RAB, probably misapplied; = Lamium purpureum L. var. incisum (Willd.) Pers. – K1, K3, NcTx, NE, Mennema (1989)
