Helminthotheca echioides (bristly oxtongue) is a winter or summer annual, or occasionally a biennial (family Asteraceae) that is native to the Mediterranean region of Europe, northern Africa, and western Asia. It has been introduced into many parts of the world, including other parts of Europe, Australia, New Zealand, North America, South America, and South Africa. In the United State, it is most common in California, where it is found especially along the coast and in the Central Valley and on clay and alkaline soils. Bristly oxtongue has a sprawling habit and leaves with thick, often hooked hairs with swollen bases, given leaves a warty appearance. Flower heads are subtended by four bristly bracts; flower color is yellow. This plant is most commonly found in agricultural and disturbed sites, where it can outcompete other vegetation.Cal-IPC Rating: Limited?
