Anthemis cotula

Anthemis cotula, also known as stinking chamomile or mayweed, is a flowering annual plant with a noticeable and strong odor. The odor is often considered unpleasant, and it is from this that it gains the common epithet "stinking". In pre-colonial times, its distribution was limited to Europe and Africa; though it was established in most of Europe, it was not present in Finland, Ireland, or the northernmost reaches of Scotland, in spite of the fact that these countries feature climatic regions favorable to this plant and are in proximity to countries where the species is native, such as Russia, Estonia, Lithuania and England. It has successfully migrated to the American continents where it can be found growing in meadows, alongside roads, and in fields. The name "cotula" is the Latin form of κοτύλη kotylē, the Greek word for "small cup", describing the shape of the flowers; it was assigned by Carl Linnaeus in his work Species Plantarum in 1753. Anthemis cotula is also known by a wide variety of other names, including mather, dog- or hog's-fennel, dog-finkle, dog-daisy, pig-sty-daisy, chigger-weed, mayweed, Johnnyweed, maroute, Maruta cotula, Cotula Maruta foetida, Manzanilla loca, wild chamomile, Camomille puante. Foetid Chamomile, maithes, maithen, mathor mayweed chamomile, camomille des chiens, camomille puante, stinkende Hundskamille, camomila-de-cachorro, macéla-fétida, and manzanilla hedionda.
