B1FDC3680DC66FC6996C9A41FD2A13CF.taxon	diagnosis	Diagnosis. Trollius austrosibiricus is morphologically close to T. chinensis Bunge and T. macropetalus (Regel) Fr. Schmidt. It differs from these species in simple rhizomes, shorter aerial shoots, smaller flowers and shorter persistent styles. The new species is distinguished from T. asiaticus L. by a smaller number of sepals, longer persistent styles and petals longer than sepals.	en	Erst, Andrey, Luferov, Alexander, Troshkina, Victoria, Shaulo, Dmitry, Kuznetsov, Alexander, Xiang, Kunli, Wang, Wei (2019): Trollius austrosibiricus (Ranunculaceae), a new species from South Siberia.
