About Erythranthe bicolor (Hartw. ex Benth.) G.L.Nesom & N.S.Fraga
Erythranthe bicolor, commonly called yellow and white monkeyflower, is an annual herb. It produces a hairy, erect stem that grows 4 to 27 centimeters tall. Its leaves range from linear to nearly oval in shape, measure up to 3 centimeters long each, and are arranged in opposite pairs around the stem. The tubular base of its flower is surrounded by a reddish-green, freckled calyx of sepals that bears small, pointed lobes. The flower corolla is 1 to 2 centimeters long and divided into two lips. Corolla color varies, but most often the upper lip is white and the lower lip is yellow. The upper lip has two main lobes, while the lower lip has three; each main lobe has two smaller sub-lobes at its tip. This species occurs in mountains and foothills from the Klamath Range through the Sierra Nevada to the Tehachapi Mountains, where it grows in moist or wet areas, often on clay soils.
