Plate XCI. Monkey-Flower. - M. ringens
From late July onward the monkey-flowers tinge the wet fields and border the streams and ponds; not growing in the water like the pickerel-weed, but seeking a hummock in the swamp, or a safe foothold on the brook's edge, where they can absorb the moisture requisite to their vigorous growth.
The name is a diminutive of mimus - a buffoon, and refers to the somewhat grinning blossom. The plant is a common one throughout the eastern part of the country.
