A new subspecies of Stellariaalsine (Caryophyllaceae) from Yakushima, Japan.

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.nana subsp. nov. was published.
