Notes
| Last seen in 1941. May have been extirpated by agriculture. Good potential for rediscovery, but field surveys in 1990-1992 and 1997 unsuccessful. See Proceedings of the American Academy of Arts and Sciences 7:385 (1867) for original description, and Annals of the Missouri Botanical Garden 12:90-91 (1925) for taxonomic treatment. |
