The specimen depicted below displays all the characteristic features of S. nemoralis, including nodding inflorescence and pubescence on the upper and lower leaf surfaces.
I identified the species below as S. nemoralis because of the nodding inflorescence and the pubescence on both the upper and lower stem. However, it is atypical because of the red stem colour and the minimal pubescence on the upper and lower leaf surfaces.
