Scorpidium in small quarry, Brecon Beacons
Asplenium viride in small quarry, Brecon Beacons
It was fortunate that I took a small sample of the Scorpidium because after checking leaf cell structure under the microscope it appears to be S. cossonii. Once upon a time they were both Drepanocladus revolvens!

The wet rocks also had small amounts of Blindia acuta and Empetrum nigrum was scattered in heathy areas above the quarry. Fascinating to think that this collection of Boreo-arctic montane species is only few miles away from an exemplary collection of hyper-oceanic species in the Upper Nedd and Mellte headstreams.
