The status and relationship among pleurocarpous families have been hardly elucidated (Buck et al., 2000; Cox et al., 2010).
However, the paraphyletic or polyphyletic condition of many pleurocarpous families makes difficult to establish a reliable sister relationship.
As can be seen from previous analyses (Cox et al., 2010; Rao, 2001), low character support in phylogenies of pleurocarpous taxa is not a weakness of the current data solely.

The pleurocarpous species Anomodon and Platygyrium thus could have usurped a majority of the substrate by growing across it, preventing the acrocarpous species (Leucobryum) from spreading once it established.
Growth form has also been postulated to lead to positive interactions: intermingling of their strands may create a network that would decrease water loss by both pleurocarpous species (Magdefrau 1982, Schofield 1985, Scandrett and Gimingham 1989, 0kland 1994), thus increasing their photosynthetic potential.
