Hymenoxys (rubberweed or bitterweed) is a genus of plants in the sunflower family, native to North and South America. [3] [1] [4] It was named by Alexandre Henri Gabriel de Cassini in 1828. [1]

Plants of this genus are toxic to sheep due to the presence of the sesquiterpene lactone hymenoxon. [5] [6] [7]
