Hypochaeris glabra is a species of flowering plant in the dandelion tribe within the daisy family known by the common name smooth cat's ear. It is native to Europe,[2] North Africa, and the Middle East but it can be found on other continents where it is an introduced species and a widespread weed. It has become widespread in Africa, southern and southeastern Asia, Australia, and parts of the Americas (especially California).[3][4][5][6]

Hypochaeris glabra is an annual herb growing a small taproot, a basal rosette of leaves, and one or more thin stems 10 to 40 centimeters (4-16 inches) tall. The leaves are 2 to 10 centimeters (0.8-4.0 inches) long, smooth along the edges or with small lobes, and green in color, sometimes with a purplish tint near the veins. Atop the thin, naked stems are flower heads with small overlapping purple-tipped phyllaries and bright yellow ray florets. The fruit is a cylindrical achene with a white pappus almost a centimeter (0.4 inches) long.[7]
