''Dietes'' is a genus of rhizomatous plants of the family Iridaceae, first described as a genus in 1866. Common names include wood iris, Fortnight lily, African iris, Japanese iris and Butterfly iris, each of which may be used differently in different regions for one or more of the six species within the genus. Most species are native to southern and central Africa, with one (''Dietes robinsoniana'') native to Lord Howe Island off the coast of Australia. A few species have become naturalized in other parts of the world.〔(Kew World Checklist of Selected Plant Families )〕 ==Taxonomy== These plants were formerly placed in the genus ''Moraea'', but were reclassified because they are rhizomatous. Like ''Moraea'', they differ from ''Iris'' in having flowers with six free tepals that are not joined into a tube at their bases. 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. grandiflora'' or ''D. iridioides.'' The genus name is derived from the Greek words ''di-'', meaning "two", and ''etes'', meaning "affinities". ;Species〔 # ''Dietes bicolor'' (Steud.) Sweet ex Klatt (Yellow Wild Iris, Peacock Flower, Butterfly Iris) - Cape Province, KwaZulu-Natal # ''Dietes butcheriana'' Gerstner Cape Province, KwaZulu-Natal # ''Dietes flavida'' Oberm. - South Africa, Swaziland # ''Dietes grandiflora'' N.E.Br. (Wild Iris, Large Wild Iris, Fairy Iris) - Cape Province, KwaZulu-Natal; naturalized in St. Helena, Mauritius, Rodrigues Island in Indian Ocean, Western Australia # ''Dietes iridioides'' (L.) Sweet ex Klatt (Wild Iris, African Iris, Cape Iris, Fortnight Lily, Morea Iris) - widespread from Ethiopia to Cape Province; naturalized in Madeira, Mauritius, Réunion, Hawaii, Jamaica # ''Dietes robinsoniana'' (F.Muell.) Klatt (Wedding Lily) - Lord Howe Island (part of New South Wales) ''Dietes bicolor'' has cream or yellow flowers. ''D. grandiflora'' and ''D. iridioides'' both have white flowers marked with yellow and violet, and appear similar in photographs, but they are quite different: those of ''grandiflora'' are much larger, last three days, and have dark spots at the base of the outer tepals, while those of ''iridioides'' are small, last only one day, and lack the spots. ''D. grandiflora'' is also a larger plant overall.
