Dysphania pumilio

Dysphania pumilio (common names - small crumbweed, clammy goosefoot) is a species of flowering plant in the family Chenopodioideae. It is native to Australia, but it is found in other parts of the world as an introduced species, often growing in disturbed and waste areas such as roadsides and lots. It is known from many parts of North America and Europe, and it was recently found in Iran for the first time, in the Māzandarān Province. It is thought to have first arrived in Europe with imports of wool from Australia....read more on Wikipedia.
