Xamilenis
is an oligotypic genus recognized in the
Sileneae
tribe since 2001. We have considered the justification of recognizing
Xamilenis
as the small segregate genus by molecular phylogeny methods. We analyzed nuclear (ITS1-5,8S-ITS2) and chloroplast (gene
trn
L intron) sequences obtained from several species of the genus from different localities and compared a number of other
Sileneae
species. Phylogeny trees were constructed via the neighbor-joining and Bayesian methods.
Xamilenis
species did not form a monophyletic clade and were closely related to the Silene species from the
Siphonomorpha
subgenus. The conception of
Xamilenis
as a segregate genus was not confirmed by the molecular phylogeny data.
