Iris subg. Limniris
Subgenus Limniris is one subgenus of beardless irises, which don't have hair on their drooping sepals, also called their falls.
It was originally described by Tausch in Deut. Bot. Herb.-Buch (Deutsche Botaniker) in 1841. Édouard Spach made changes 1846 in Ann. Sci. Nat., Bot. (Annales des Sciences Naturelles; Botanique). 
It was divided into sections, 'Limniris', which is further divided down to about 16 series and 'Lophiris' (also known as 'Evansias' or crested iris). They are both polyphyletic. It has 45 species, which are widely distributed in the Northern Hemisphere.
Various authors have tried to classify the list in various ways. It is still undergoing study and variations.
