|discussion=<p><i>Madia gracilis</i> occurs widely in California (except the warm deserts), is scattered across much of <i>Nevada</i>, Oregon, and Washington (outside the driest regions), and extends into southernmost British Columbia, north-western Montana, and northern Utah. Near the coast, <i>M. gracilis</i> sometimes co-occurs with <i>M. sativa</i>; the two species are partially interfertile (<i>M. gracilis</i> tends to flower earlier than <i>M. sativa</i>; J. Clausen 1951). Reported occurrences of <i>M. gracilis</i> in Maine and South America have not been confirmed.</p>
