Kazakhstan Has an Unexpected Diversity of Medicinal Plants of the Genus (Acoraceae) and Could Be a Cradle of the Triploid Species .

The group, or sweet flag, includes important medicinal plants and is classified into three species: (diploid), (tetraploid), and (sterile triploid of hybrid origin). Members of the group are famous as components of traditional Indian medicine, and early researchers suggested the origin of the sweet flag in tropical Asia. Subsequent research led to an idea of the origin of the triploid in the Amur River basin in temperate Asia, because this was the only region where both diploids and tetraploids were known to co-occur and be capable of sexual reproduction.

Karyotype and genome size variation in white-flowered sect. (Ranunculaceae).

Comparative karyomorphological analyses of six out of the eight white-flowered species of Eranthissect.Shibateranthis have been carried out. All studied specimens of , , , and had a somatic chromosome number 2 = 16 with basic chromosome number = 8.

An integrative taxonomic approach reveals a new species of (Ranunculaceae) in North Asia.

A new endemic species, , is described from the Republic of Buryatia and Irkutsk Province, Russia. It belongs to Eranthis section Shibateranthis and is morphologically similar to and . An integrative taxonomic approach, based on cytogenetical, molecular and biochemical analyses, along with morphological data, was used to delimit this new species.
