Discussion | Erythronium rostratum 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 Erythronium with erect rather than nodding flowers. Some plants at the western limits of the range are triploids (B. L. Carr 1986). (Discussion copyrighted by Flora of North America; reprinted with permission.) |
