Parthenium hysterophorus[2][3]

Parthenium is a genus of North American shrubs in the sunflower tribe within the daisy family.[4][3]

The name Parthenium is derived from either the Greek word παρθένος (parthenos), meaning "virgin," or παρθένιον (parthenion), an ancient name for a plant.[5]

Members of the genus are commonly known as feverfew.[6] Notable species include Guayule (P. argentatum) which has been used as a rubber substitute, especially during the Second World War;[7] and also P. hysterophorus, a serious invasive species in the Old World.[8]

In North America, the Jicarilla Apache people used Parthenium incanum for medicine (Opler 1946: 8). The sap of Guayule (P. argentatum) is a source of natural rubber.[9] It is often mistaken for marijuana because of it being referred to as a "weed".
