About Diplacus rupicola (Coville & A.L.Grant) G.L.Nesom & N.S.Fraga
Diplacus rupicola, also called the Death Valley monkeyflower, is a perennial herbaceous plant. It reaches 1 to 17 centimeters in height, and bears oblanceolate leaves that are 2 to 6 centimeters long. Its flowers are pinkish, often with a faint pale color, and each lobe of the flower has a magenta-purple spot. This plant is endemic to the northern Mojave Desert, located within Inyo County in eastern California. While it is quite rare, it can be found growing in shaded limestone crevices on steep canyon walls of the mountains that border Death Valley, and on the sky islands of the northern Mojave Desert.
