Carpets and hummocks of Opposite-leaved Golden-saxifrage

Looking back over this blog I notice that on Valentine's Day we wrote about the tame wood and illustrated the piece with a couple of photos of Opposite-leaved Golden-saxifrage. It has quite a limited distribution in Orkney - in Elaine Bullard's 'Wildflowers in Orkney' (1995) she considers it to be 'rare' and occurring in just five of Elaine's 'islandised squares': 20 (north Hoy and Graemsay), 29 (south Hoy), 30 (Orphir), 31 (Stenness, Firth and Harray) and 40 (St Ola and Holm). On my travels today I found a quite substantial carpet of it adjacent to the Wideford Burn (that'll be 'islandised square' 40). The carpet undulated over rounded hummocks and on a grey afternoon was a vivid and luminous green yellow. It was some sight.
