I would say that the species is rare in the locality, however by chance I did find a small population on Holme Stinted Pastures which was partially hidden and protected by the multitudes of bracken in the vicinity.
Although I am fairly familiar with most hypericum species, at first I was thrown into confusion with never having seen the species until that day (16th July 2021). I have made notes and will try and do more studies on this next year.
