D. B. Lellinger (1985) applied the name Thelypteris interrupta to specimens from India, while using T . totta (type from South Africa) for North American and South American specimens. Diploid cytotypes are known from Africa and Asia, whereas all counts from the Neotropics are tetraploid. Until more counts are available and the morphologic variation (chiefly in glands, pubescence, and leaf size) in this species complex is better understood, I prefer to circumscribe the species broadly.
R. E. Holttum (1982) circumscribed Cyclosorus (as a genus) to include this species and one or two others.
