places from N. Eng. to Pa., Del., and Ga. Not com- 

 mon. 18-28 inches high or more. In the var. crispa the 

 plant is smooth, but the green flower-cup is hairy; it has 

 also torn-toothed leaves somewhat curled. Swamps and 

 roadside ditches. Southern N. Y., N. J., and Pa. 



The tiny bell-shaped flowers clustered in 

 circles about the plant-stem at the junc- 

 tion with leaf-stems. Leaves ovate, blunt- 

 toothed, and distinctly stemmed. Not a 

 common species. 6-20 inches long. Found 

 in moist fields. N. Eng., N. Y., and Pa., south. 



The only native mint. The lilac-white 

 or white flowers oblong bell-shaped, with 

 a short-toothed edge ; the clusters ar- 

 ranged as in the preceding species. 

 Leaves conspicuously tapering from the 

 centre toward both ends, coarsely toothed, 

 ovate-oblong or lance-shaped, and rough- 

 ish, or nearly smooth. The plant is more 

 or less hairy throughout, and has the odor of Penny- 

 royal. In wet places south to Va., and through the 

 northern United States across the continent. 10-28 in- 

 ches high. This mint, according to Prof. Charles Robert- 

 son, is visited in Illinois b}^ the fly Jurinia smaragdina. 

 A mintlike weed with small white 

 flowers remotely suggesting a bugle 

 shape. Stem slender, four-angled, and 

 generally smooth. The light green leaves 

 ovate lance-shaped and very coarsely 

 toothed. The tiny flowers clustered at 

 the bases of the leaves have but two perfect stamens ; 

 the other two, if present, are quite abortive. Fertilized 

 mostly by the beelike flies, and the small bees of the 

 genus Halictiis. 6-24 inches high. Common. 



A similar species, with some leaves so 

 deeply toothed that they appear incised, 

 and others incised to an appearance of 

 lobes. The stiff stem generally smooth, 

 simple or branched. The flower-cup tiny 

 and but little larger than its green calyx. 

 1-2 feet high. Common.
