A daytrip to Meirionydd involved visits to three waterfalls/streams. The nicest was a couple of km from the famous Coed Ganllwyd - Wales' top oceanic ravine - and although it didn't live up to its neighbour's richness it did hold plenty of lovely bryophytes. These included Jamesoniella autumnalis (photo) on an old Birch, Mylia taylori (photo) on a rotting log, Lepidozia pearsonii (photo) on a mossy slope, locally frequent Plagiochila punctata, P. spinulosa and P. bifaria, abundant Bazzania trilobata and Dicranodontium denudatum, Hygrobiella laxifolia and Jungermannia paroica by the stream, Blepharostoma trichophyllum on a rockface, and probably best of all a few shoots of Tritomaria exsecta on a rotting log. The lack of tiny Lejeuneaceae and Sematophyllum demissum was a disappointment, but it's a surprisingly long rocky valley and I only had an hour there.
