Trixis is a genus of shrubs in the family Asteraceae, native to North and South America including the West Indies.[3][4]
Members of the genus are commonly known as threefolds[5] due to the outer lip of the corolla. The generic name is derived from τριχος (trixos), the Greek word for 'threefold'.[6][7]
