Erythranthe shevockii is a rare species of monkeyflower known by the common name Kelso Creek monkeyflower. It was formerly known as Mimulus shevockii.[2][3][4][5]
Erythranthe shevockii is an annual herb up to about 12 centimeters tall with a very slender, often red stem. The oppositely arranged oval leaves are no more than a centimeter long each and are sometimes fused together in pairs about the stem.
The tubular base of the flower is encapsulated in a red or red-spotted calyx of sepals. The flower has a narrow tube throat and wide face, and is roughly a centimeter long. The corolla is divided into a deep maroon red upper lip and a wider lower lip which is yellow with red dots.
