Picris echioides, bristly ox-tongue, is a stiff annual or biennial herb native to Europe and North Africa. It was traditionally used as an antihelminthic treatment .[4]
P. echioides may grow up to 90 cm (35 in) tall, with a thick, furrowed stem and spreading branches. The leaves are 10–20 cm (4–8 in) long, oblanceolate with a short petiole. The leaves, branches and stem are all covered in thick bristles. The inflorescences are 2–3.5 cm (0.8–1.4 in) wide and subtended by between 3 and 5 large ovate-cordate involucral bracts .[5] These large bracts are the defining feature of the genus Helminthotheca, to which P. echioides may be assigned .[6]
A number of infraspecific taxa are recognised, varying in their leaf shape .[7]
Picris echioides is native to the Mediterranean Basin, but has become widely naturalised outside that range.
