Abstract

An unknown taxon of Stellaria was discovered in Yakushima, a Japanese island known to harbor several endemic species. To determine the identity of this taxon, this study employed MIG-seq for the reconstruction of a finely resolved phylogenetic tree of the newly discovered taxon, along with some related species of Stellaria. The results showed that the newly discovered taxon is a relative of S.alsine. Based on this result, Stellariaalsinesubsp.nanasubsp. nov. was published.
