Salsola tragus (weed) L. - (Russian thistle)

This herbaceous weed is native to Central Asia and eastern parts of Europe, but has become established in other parts of Europe and Asia, in the Americas, Africa and Australia. In the invaded areas it has often become a weed of rangelands and dryland crops. It grows to a height of about ½ to 1 m, mainly on sandy, often also on arid and alkaline soils. Although it can contain oxalates, livestock can tolerate it in moderate amounts. It might also harbour viruses affecting crops.

The closely related Salsola australis is considered to be a synonym of Salsola tragus by some authors.
