Cock's Foot

To continue the grassy theme, this is one of the easier to identify of the common grasses: cock's foot, orchard grass or Dactylis glomerata. (No prizes for guessing where this was growing.)
It is a key plant in one of the National Vegetation Classification categories (MG1) along with false oat-grass.
The National Vegetation Classification (NVC): now there's a thing. Very important in ecological circles!
