Rank Reasons

The distribution is disjunct into two parts. The northern range runs from California to British Columbia (Canada). The southern range extends from Santiago (Chile) and Mendoza (Argentina) down to Tierra del Fuego. It has been reported to be an introduced weed in other states fo the United States (Moldenke 1941; Cronquist 1980), and in New South Wales and Victoria in Australia, (Jacobs and Pickard 1981; Ewart and Tovey 1909). There is little doubt that M. sativa originated in western North America because this is the center of diversity of the whole Subtribe Madiinae.

Range Extent Comments

Native to Southern Cordillere of Chile and Argentina. It was introduced to France as an oil plant in the 19th century.
