Short-Fruited Willowherb (Epilobium obscurum)

Observation - Short-Fruited Willowherb (Epilobium obscurum) - UK and Ireland. Description: Two distinctly different Willowherb (Epilobium) plants growing next to each other in wet ground. On the right is the common Broadleafed Willowherb (E. montanum). On the left is, I think, Marsh Willowherb (E. palustre). E. palustre is a more slender plant

Two distinctly different Willowherb (Epilobium) plants growing next to each other in wet ground. On the right is the common Broadleafed Willowherb (E. montanum). On the left is, I think, Marsh Willowherb (E. palustre). E. palustre is a more slender plant with narrower leaves. This is a typical site for it at the edge of an acid bog.
Edit: Changed to match Cicuta's ID. Many thanks.
