Family, Figwort. Color, white, often with a pink or purplish tinge. Calyx, of 5 sepals. The mouth of the inflated, tubular corolla is a little open, the upper lip being swollen as if humpbacked. Looking into the throat, it is seen to be woolly-bearded, having 4 stamens which have woolly filaments and tiny heart-shaped anthers. A fifth but sterile stamen is present. Leaves, opposite, sessile, or with short petioles, broad below, narrower above, sharply serrate. In wet places, as edges of swamps or banks of ponds or streams. July to September.
This plant grows often very high, usually 2 to 3 feet. Stem and leaves smooth. Flowers occupy the ends of branches, crowded together, the lower in blossom while the upper are in bud. It takes a lively imagination to invest the innocent corolla with reptile-like features. (See illustration, p. 126.)
