The Curious Case of Fritillaria sonnikovae (Liliaceae) in South Siberia: New Insights into Its Origin and Phylogeny

Fritillaria Tourn. ex L. is a genus of Liliaceae including little more than 150 species occurring in the temperate Holarctic. sonnikovae Shaulo & Erst most recently described Siberian genus. In affinity section F. diagnosis, only dagana Turcz. and roylei Hook. are mentioned. Our study an original attempt to shed light on origin its evolutionary relationships with other using nuclear (ITS) plastid (matK + rps16 trnH-psbA) DNA markers. results showed that together maximowiczii Freyn belongs North Asian lineage Liliorhiza subgenus produced no evidence supporting relationship between roylei. Monophyly was not reliably confirmed our since close demonstrated by phylogenetic analysis morphology. shown be sister group. Most authors present suggest considering as synonym for maximowiczii. this view, may considered narrow endemic one light-perianth morphs maximowiczii, which has emerged Western Sayan remained there tertiary relict.
