 Lycopus communis Bicknell, Britton Man. 803. 1901. 



Green or sometimes purplish, mostly less pu-

 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-

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

 obtuse; corolla about ii" 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.
