Madia gracilis is a species of flowering plant in the aster family known by the common names grassy tarweed and slender tarweed.
Range
Madia gracilis is native to western North America from British Columbia to Baja California to Utah, where it grows in many habitat types except for arid areas.
Description
The Madia gracilis plant is variable in appearance. In general, it is an aromatic annual herb growing up to a meter in height, its stem branching and hairy and glandular in texture. The leaves are up to 10 centimeters long and covered in soft hairs and stalked resin glands.
The inflorescence is an array of clusters of flower heads. Each head is lined with phyllaries that are coated densely with stalked knobby resin glands. It bears yellow, lobe-tipped ray florets a few millimeters long and several black-anthered disc florets. The fruit is a flat, hairless achene with no pappus.
