This is one of the difficult members of this tricky genus to identify. It is usually quite hairy or hoary (see RHS photo) as the name suggests but not always. It does have slightly toothed leaves and a four-lobed stigma but varies quite a bit in appearance. The flowers are not small as you might think from parviflorum but just about the same size as other medium sized willowherbs.

It is found throughout England, Wales and Ireland but becomes scarce in the highlands of Scotland.
