Other claims from this paper (5)
- Observation A new genus and species, Ombronesus stuvensis, of the Ptychomniaceae was described from Juan Stuven Island.
- Observation Molecular phylogenetic analyses and morphology independently confirm the position of Ombronesus stuvensis in the family Ptychomniaceae.
- Observation Ombronesus stuvensis is clearly distinct from previously described genera, based on a highly reduced endostome, a unique combination of gametophytic characters and molecular autapomorphies.
- Observation The Ptychomniales occupy a key phylogenetic position as one of the earliest diverging pleurocarpous lineages, with features intermediate between basal orthotropic and derived plagiotropic pleurocarps.
- Observation The new taxon contributes to the nature conservation value of the locality on Juan Stuven Island.
