The three species of Liverwort that I've so far found in Wilton Lodge Park, Hawick, starting from the waterfall of the Cala Burn downstream.
Lunularia cruciata inhabits the section nearest to the waterfall and then it's the turn of Conocephalum conicum. The latter covers a larger expanse on both sides of the burn, slowly petering out as the terrain opens out and overhead cover decreases. Marchantia polymorpha is the furthest downstream and is in the most open situation, occupying a flat area just to the side of the burn but not actually on its banks.
Finally a bonus Lichen that shouted at me as I returned to the car.
