This plant caught my eye Was it a dead nettle? Was it a hemp nettle? Black Horehound? Northern Deadnettle?

Had a look at its features as recorded in my photos, several observations on this site and elsewhere and my two books, Averis - Plants and Habitats, and Rose - Wildflower Key. A strong element of uncertainty as I've not explored Lamiaceae at all. When is a pointed calyx tooth referred to as spiny? How hairy is hairy? How coarse is a coarse toothed leaf?!! I do need some help with this one, but wanted to do some of the work!
