Distichium

Distichium is a genus of haplolepideous mosses (Dicranidae) in the monotypic family Distichiaceae.

Taxonomy
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).
