Lycopus communis Bicknell, Britton Man. 803. 1901. 
Green or sometimes purplish, mostly less pu- 
berulent than L. virginicus; stems rather slender, 
simple or sparingly branched, 4’—23° 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, 7’-32’ long, sessile or nearly so; calyx-teeth 
4 or 5, triangular, ovate or ovate-oblong, rather 
obtuse; corolla about 13” 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.
