Prickly Russian Thistle

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 species of tumbleweed. Informally, it also is known as "salsola", which was its generic name until fairly recently.
