|discussion=<p><i>Erythronium rostratum</i> is found mostly on either side of the Mississippi River embayment, but rarely within it. It often forms extensive colonies where nonflowering, 1-leaved plants far outnumber flowering ones. This is the only species of <i>Erythronium</i> with erect rather than nodding flowers. Some plants at the western limits of the range are triploids (B. L. Carr 1986).</p>
