Lowell Randolph (a Cornell University botany professor) had collaborated with Ira S. "Ike" Nelson since 1942, after the first show of the 'Society for Louisiana Irises' was held. They both identified a new iris from Abbeville, Louisiana. Randolph named the new iris after him.[2][3]Iris nelsonii was then first published and described by Randolph in 'Baileya' (a Quarterly Journal of Horticultural Taxonomy of Ithaca, New York) 14: 150 in 1966.[4]
