This is a local species of various habitats. I have specimens from dry oak slopes, moist sugar maple and beech woods, and from hard white clay soil in a sweet gum "flat" in Clark County where I found specimens 5 feet high.
Stem 5-8 dm, hirsute on the angles only with pustulate hairs 1-2 mm deflexed at 45л lvs lance-ovate to oblong, 6-12 cm, acuminate, sharply serrate, obtuse to subcordate at base, hirsutulous on both sides; petioles slender, 1-3 cm, smooth on the upper side; verticils usually 6- fld; cal-tube hairy, 3.3-5.3 mm, the lobes deltoid-acuminate, half as long, tapering to a subulate tip 1 mm. Mostly in mt. woods at high altitudes; Va. and W.Va. to N.C. and Tenn.; plants from Ill. and Ind., with the bristles scarcely deflexed, are also referred here.
