Veronica scutellata is a species of flowering plant in the plantain family known by the common names marsh speedwell, grassleaf speedwell, and skullcap speedwell. It is native to northern North America, including most of Canada and the northern half of the United States. It occurs in moist and wet habitat, such as ponds, marshes, and other wetlands. It is a rhizomatous perennial herb producing a decumbent or upright stem 40 to 60 centimeters in maximum height. It is mostly hairless in texture. The purple-green or reddish leaves are oppositely arranged in pairs about the stem, the blades lance-shaped and smooth-edged. The inflorescence is an open array of several flowers on thin, straight pedicels. The flower is up to a centimeter wide with four lobes, the upper lobe being largest.
