Epipactis persica (Orchidaceae), a new taxon for the flora of Kazakhstan, Kyrgyzstan and China

The paper provides information about Epipactis persica, a new species for the flora of Kazakhstan, Kyrgyzstan and China. New localities of this species are based on herbarium material stored in herbarium collections AA, KUZ, LE, MW, NUR, and TASH, personal field records, and observations published on iNaturalist. Localities in Kazakhstan represent the northernmost records of E. persica, but its possible presence in Russian Siberia is discussed. In China, E. persica is currently reported based only on historical herbarium collections dated by 1877–1879.
