Salsola tragus

Species of flowering plant

Salsola tragus, often known by its synonym Kali tragus is a species of flowering plant in the family Amaranthaceae. It is known by various common names such as prickly Russian thistle, windwitch, or common saltwort. It is widely known simply as tumbleweed because, in many regions of the United States, it is the most common and most conspicuous plant species that produces tumbleweeds. Informally, it may be known as "'Kali or Salsola": the latter being its restored genus, containing 54 other species, into which the obsolete genus Kali has been subsumed.
