Parthenium
Parthenium
Genus of shrubs
Parthenium is a genus of North American annuals, biennials, perennials, subshrubs, and shrubs in the tribe Heliantheae within the family Asteraceae and subfamily Asteroideae.[4][2][3][5]
The name Parthenium is an evolution of the Ancient Greek name παρθένιον (parthenion), which referred to Tanacetum parthenium.[6][7][8] The name is possibly derived from the Greek word παρθένος (parthenos) which means "virgin".[5]
Members of the genus are commonly known as feverfew.[9] Notable species include guayule (P. argentatum) which has been used as a rubber substitute, especially during the Second World War;[10] and also P. hysterophorus, a serious invasive species in the Old World.[11]
