Trixis is a genus of shrubs in the aster family, Asteraceae, native to North and South America including the West Indies.[4][5]

Members of the genus are commonly known as threefolds[6] due to the outer lip of the corolla. The generic name is derived from τριχος (trixos), the Greek word for threefold.[7][8]
