Least Pepperwort

Lepidium virginicum L. is an herbaceous plant in the mustard family (Brassicaceae). It is native to much of North America and has been introduced to other parts of the world. The species was first published in 1753 and has been the subject of taxonomic debate. Some authors, such as Vasconcellos, treated it as a synonym of L. graminifolium L., but typification clarified its status, avoiding a name change. It is also known as Virginia pepperweed and is widely distributed across the United States, Mexico, Canada, and Central America.
