A plant of Europe and Asia Minor, with us characteristically a weed of railroad embankments, but also common on roadsides, parking lots, gravel pits, and other sandy or gravelly bare places. First collected in 1870 in Genesee Co.
This little densely stellate-pubescent annual is likely to be confused only with Lepidium, in which, however, the fruit is flattened at right angles to the septum rather than parallel to it.
