Hirschfeldia incana (formerly Brassica geniculata) is a species of flowering plant in the mustard family known by many common names, including shortpod mustard, buchanweed, hoary mustard^[3] and Mediterranean mustard.^[4] It is the only species in the monotypic genus Hirschfeldia, which is closely related to Brassica.^[5] The species is native to the Mediterranean Basin but it can be found in many parts of the world as an introduced species and often a very abundant noxious weed.^[6] This mustard is very similar in appearance to black mustard, but is generally shorter.^[7] It forms a wide basal rosette of lobed leaves which lie flat on the ground, and it keeps its leaves while flowering.^[8] Its stem and foliage have soft white hairs. Unlike black mustard, H. incana is a perennial plant.^[7]
