The genus
Distichium has traditionally been considered part of family
Ditrichaceae. However, phylogenetic analyses have found Ditrichaceae to be polyphyletic and
Distichium part of a protohaplolepidous grade of early branching lineages in
Dicranidae. Based on these studies
Distichium was restored to Distichiaceae, where it was originally placed by Schimper (1860). ==Species==
