348 LABIATAE (MINT FAMILY) 
Not a woodland plant in spite of its name. Stem one to three 
feet high, slender, erect, simple or with few branches, covered 
with fine, appressed hairs. Leaves long- 
ovate to lance-shaped, green above, ap- 
pressed gray-hairy beneath, sharply toothed, 
narrowing to short petioles. Flowers in 
long, crowded racemes, six inches to a 
foot in length, making the plant con- 
spicuous when growing in meadows; calyx 
densely velvety-hairy, five-toothed ; corolla 
pink or rose-purple, the lower lip with one 
large, rounded spreading lobe and two 
small pointed ones; upper lip deeply cleft, 
the exserted stamens and style thrust out 
between its lobes; the blossoms are often 
nearly an inch long, in whorls of six or 
more, on very short pedicels, subtended by 
leafy bracts about as long as the calyx. 
Nutlets obovoid and rough. (Fig. 240.)

cut closely and repeatedly during the growing season, so as to 
starve the roots and prevent seed production.
