Research published in 1988 showed that is a hybrid of P. ellipticum and P. insigne via an allopolyploid process, previously considered to be absent in bryophyte evolution.^[5]

In the UK it is classified as near threatened. More than 10% of all UK populations occur in the Cairngorms National Park in Scotland including sites in the Lairig Ghru and on the plateau of Lochnagar.^[6]
