 These plants were formerly placed in the genus "Moraea", but were reclassified because they are rhizomatous.Some references mention the species "Dietes vegeta" or "D. vegeta variegata", springing from some confusion with "Moraea vegata" (which grows from a corm, not a rhizome).The name "D. vegeta" is commonly misapplied to both "D. iridioides" and "D. grandiflora".
