DistributionEriophyllum congdonii is native to the mountains of central Mariposa County, California, where it grows along the valley of the Merced River as it flows through Yosemite National Park. One additional population has been reported on the east flank of Telescope Peak in Inyo County.[1]DescriptionEriophyllum congdonii is an annual herb growing mostly erect with branching stems up to 30 centimeters (1 foot) long. The woolly, whitish leaves are 1 to 4 centimeters (0.4-1.6 inches) long and may have a few shallow lobes.[3][2]The inflorescence consists of one flower head containing many glandular yellow disc florets surrounded by 8 to 10 yellow ray florets each 3 to 5 millimeters (0.12-0.20 inches) long.[3] The fruit is a rough-haired achene with a tiny, scaly pappus.[3] See also
