Pentanema britannica, the British yellowhead or meadow fleabane,[1] is a Eurasian species of plant in the daisy family. It is widespread across much of Europe and Asia, and sparingly naturalized in scattered locations in North America.[2][3][4]

Pentanema britannica is an erect herb up to 75 cm (30 inches) tall, with fine hairs but not the thick woolly coat characterizing some related species. Leaves are lance-shaped, up to 5 cm (2 inches) long. One plant produces a few heads, each on a long flower stalk. Each had contains 50-150 yellow ray flowers and 100-250 yellow disc flowers.[5]

The plant produces the flavonol axillarin.[6]
