Jensia yosemitana (syn. Madia yosemitana) is a species of flowering plant in the aster family known by the common name Yosemite tarweed.[2] It is endemic to California, where it has a scattered distribution across the Sierra Nevada and its foothills.[3]
Jensia yosemitana is an annual herb with a slender stem up to 25 centimeters tall. The hairy to bristly leaves are 1 to 3 centimeters long and located all along the stem. The inflorescence produces flower heads on thin, threadlike peduncles. The head generally has 2 or more yellow ray florets each about 2 millimeters long and yellow disc florets tipped with black anthers. The fruit is an achene with a bristly or scaly pappus.[4]
