LAMIUM (Greek for throal, referring to the shape of 

 the corolla). Labiats: Dead Nettle. Annual and 

 perennial herbs of the Old World, of which several 

 nin wild in this country as weeds and others are culti- 

 vated as hardy border plants. . , , , o v „o.i 

 Botanically, Lamium is distinguished by a 2-lipped 

 corolla, of which the tube is somewhat longer than the 

 calvx, the upper lip ascending and concave, and the 

 lower one 3-lobed: stamens 4, in 2 pairs, ascending 

 under the upper lip: fls. in axillary or terminal whorls, 

 often rather shoNvy: lvs. opposite mostly crcnate- 

 dentate and petiolate: calyx awl-toothed.— Low herbs, 

 of some 40 species in Eu., N. Afr. and Asia. 



Lamiums are diffuse mostly pubescent or hairy herbs, 

 commonly decumbent at the base and often almost trai - 

 ine They are of the easiest culture in any open soil. 

 U.seful for rockwork. The cultivated kinds are peren- 

 nial, and are commonly propagated by division.
