MINT FAMILY 



2, Lycopus uniflorus Michx. Northern 

 Bugle-weed. Fig. 3674. 



Lycopus uniflorus Michx. FI. Bor. Am. i: 14. 1803. 

 Lycopus communis Bicknell, Britton Man. 803. 1901. 



Green or sometimes purplish, mostly less pu- 

 berulent than L. virginiciis; stems rather slender, 

 simple or sparingly branched, 4'-2 tall, rather 

 acutely angled, tuberous at the base, the stolons 

 rarely tuber-bearing. Leaves oblong or oblong- 

 lanceolate, acute or acuminate at the apex, ser- 

 rate, f'-3f long, sessile or nearly so; calyx-teeth 

 4 or 5, triangular, ovate or ovate-oblong, rather 

 obtuse; corolla about il" long, less than twice as 

 long as the calyx; rudimentary posterior stamens 

 obsolete or minute; nutlets about as long as the 

 calyx, oblique at the apex. 



In low grounds, Newfoundland to British Colum- 

 bia, North Carolina, Nebraska and Oregon. Sum- 

 mer and fall. 



Lycopus membranaceus Bicknell, with thinner, 

 often coarsely-toothed, longer-petioled and larger 

 leaves, appears to be a race of this species.
