S. hyssopifolia Michx. Fl. Bor. Am. 2: 4. 1803. 
Perennial, glabrous or very nearly so through- 
out, sometimes slightly hirsute at the nodes; 
stem slender, usually branched, erect or nearly 
so, 1°-14° long. Leaves thin, linear, acute at 
FZ both ends, or the uppermost rounded at the 
base, short-petioled or sessile, entire, or spar- 
ingly denticulate with low teeth, 1-2’ long, 
1’-24”" wide, the uppermost reduced to short 
floral bracts; clusters few-several-flowered, 
forming an interrupted spike; calyx glabrous 
or slightly hirsute, 2”-3” long, its teeth lan- 
ceolate-subulate, nearly as long as the tube; 
corolla about 7” long, light purple, glabrous. 
In fields and thickets, Massachusetts to Florida, 
Indiana, Michigan and Virginia. July—Sept. 
2. Stachys atlantica Britton. Coast Hedge Nettle. 
Fig. 3616. 
Stachys atlantica Britton, Man. 792. 1901. 
Perennial, glabrous or with a few hairs at the nodes of 
the stem, weak, diffuse, 8’-16’ long. Leaves thin, oblong 
or linear-oblong, obtuse or obtusish at the apex, narrowed, 
or the upper sometimes rounded at the base, remotely den- 
ticulate or entire, spreading, 2’ long or less, 2’-5’’ wide; 
fruiting calyx glabrous, broadly campanulate, about 23” 
long, its teeth triangular-ovate, acuminate, more than half 
as long as the tube; corolla purplish. 
In wet meadows and marshes, Long Island to eastern Penn- 
sylvania. Perhaps a wet-ground race of the preceding species. 
Aug.—Sept.

or linear, pubescent or glabrate, acuminate or 
acute at the apex, narrowed at the base, 2’-10” 
wide, 1’-3’ long, serrulate; clusters in a terminal 
rather dense spike, and usually also in the upper 
axils; calyx more or less hirsute, 24” long, its 
lanceolate-subulate teeth more than one-half as 
long as the tube; corolla nearly as in S. hyssopi- 
folia. 
In moist soil, Massachusetts to Pennsylvania, 
Georgia, Wisconsin and Kentucky. July—Aug.
