Lomatium cous (cous biscuitroot)[1] is a perennial herb of the family Apiaceae. The root is prized as a food by the tribes of the southern plateau of the Pacific Northwest. Meriwether Lewis collected a specimen in 1806 while on his expedition. [2]

It is called x̣áwš in the Sahaptin language, and qáamsit (when fresh) and qáaws (when peeled and dried) in the Nez Perce language.
