According to phylogenetic analyses of nrDNA ITS1 and ITS2 sequences (including the 5.8S unit) Plagiochila carringtonii and P carringtonii subsp, lobuchensis form a monophyletic lineage, Plagiochilo carringtonii is sister to P sandei, type species of P. sect. Cucullatae, and is placed in a clade with P. asplenioides and P porelloides of sect. Plagiochila. A placement of Plagiochila (Adelanthus) carringtonii in another genus is clearly rejected by Kishino-Hasegawa-tests. Infraspecific ITS variation in Plagiochila can be high and potentially provides a tool for the analysis of dispersal events.
