Jensia yosemitana is a species of flowering plant in the family Asteraceae known by the common name Yosemite tarweed.[3] It is endemic to California, where it has a scattered distribution across the Sierra Nevada and its foothills. Some of the populations lie inside Yosemite National Park.[4][5]

Jensia yosemitana is an annual herb with a slender stem up to 25 centimeters (10 inches) tall. The hairy to bristly leaves are 1 to 3 centimeters (0.4-1.2 inches) long and located all along the stem. The inflorescence produces flower heads on thin, threadlike peduncles. The head generally has 2-8 yellow ray florets each about 2 millimeters (0.08 inches) long and 1-7 yellow disc florets with black anthers. The fruit is an achene with a bristly or scaly pappus.[6]
