Parentucellia viscosa is a species of flowering plant in the broomrape family. It is native to Europe, but it can be found on other continents, including New Zealand, Australia and North America, as an introduced species. This is an erect annual herb producing a stiff, slender stem coated in hairs and sticky glands. It reaches a maximum height of 50 to 70 centimetres. The hairy leaves are lance-shaped to oval and are lined with several teeth. The inflorescence is a raceme of flowers at the end of the stem. The flower is tubular, the calyx of sepals extending along most of the length of the corolla, which may exceed 2 centimetres long. The lobed, lipped corolla is yellow in colour and glandular and sticky in texture.
