This collection contains records for both organizations. Most of the correspondence comes from the Secretary's files. Someone connected with the University of Southwestern Louisiana (Southwestern Louisiana Institute, now the University of Louisiana at Lafayette) usually held this position: Ira S. Nelson, Marie Caillet, Aline Arceneaux and Barbara Nelson. Scattered files from several of the society's presidents are also included: R.S. Abbott, Ray Cornay, Charles W. Arny, Jr. and Nolan John Sahuc. Much of the Society's effort was expended on the annual show held in Lafayette usually during April. The correspondence and the financial records both relate heavily to this annual event.

The newsletters were an important vehicle of communication. For the Society for Louisiana Irises, each newsletter mailing included rules and regulations for the flower show, schedules for the annual meeting and flower show, annual meeting minutes, bibliography updates, test garden results, etc. For clarification, these items have been separated from the Bulletins and arranged by subject. Both societies published much information about the care and treatment of Louisiana irises either as part of the newsletter series or separately.

The bulk of the material is dated on or before 1965. The Society for Louisiana Irises donated this collection, which made UAAMC the official repository for its records. Only a few newsletters came after.
