Stems rather stout, 11/2 to 31/2 feet high, finely pubescent or smooth below. Leaves thin, opposite, ovate to ovate-lanceolate, pointed at the apex, sharply toothed, 11/2 to 3 inches long, the upper leaves smaller, white-canescent beneath, the upper leaves usually white-canescent on both sides. Flowers in loose terminal and axillary clusters, 1 to 11/2 inches broad, canescent. Calyx slightly two-lipped, with very slender somewhat unequal teeth; corolla white with purple dots, about one-half of an inch long, two-lipped, the tube of the corolla equaling or longer than the calyx.
Dry thickets, open woods and hillsides, Maine to Ontario, south to Florida, Alabama and Missouri. Flowering from August to October.
At least six other species of this genus occur in New York, most of them are less conspicuous than the one here described and illustrated.
