 entire. Filaments not ap])endagcd : anther-cells parallel or sometimes divergent ; valves 

 naked. Nutlets smootii, truncate at apex. Leaves cleft or incised, veiny, all longer than 

 the capitate-verticillastrate flowers. 



48. LAMIUM. Calyx tubular- or turbinate-campanulate, somewhat 5-nerved, commonly

 tiu'oat; ujjper lip ovate or obh)ng, fornicate, narrowed at base ; lower lip si>rea(ling, its 

 lateral lobes truncate down to the throat, or sometimes oblong, and with or without a

 at base. Filaments not ai)pendaged : anthers approximate in pairs; their cells oblong, 

 divaricate, sometimes hairy ; valves not ciliate. Nutlets truncate at the apex. Leaves 

 mostly cordate. 



49. GALEOP3IS. Reseml)les Lainium in habit and Sinchi/s generally in flowers. But 

 anthers transversely 2-valved ; the imier valve of each cell hirsnte-ciliate, the outer and 

 larger one naked.
