Other claims from this paper (7)
- Observation Molecular analysis places Pseudoditrichum in a clade with Chrysoblastella chilensis in the haplolepideous lineage.
- Observation The results reject the earlier hypotheses on the systematic position of Pseudoditrichum.
- Observation The peristome of Pseudoditrichum is of a previously unknown type, based on the 4:2:3 formula rather than the 4:2:4 formula.
- Observation Molecular phylogenetic analysis confirms the polyphyly of Ditrichaceae.
- Observation Ditrichum flexicaule and D. gracile are segregated into the new genus Flexitrichum and family Flexitrichaceae.
- Observation The independent status of the recently resurrected family Distichiaceae is supported.
- Observation Segregation of Chrysoblastella and Saelania into new monospecific families is proposed.
