Branching dichotomous and apical. Powered by the open source Biodiversity Informatics Platform. Similar species Although the dumortiwr of receptacles shows that Dumortiera is a member of the Marchantiales, it differs from most other large thallose liverworts of this advanced order by lacking obvious air chambers and pores on the upper surface of the thallus.
