Hi all!
I browsed at a meadow outside the city and found there 4 types of plants similar to the Phalaris tuberosa and Phalaris arundinacea. But I'm not sure - I correctly identified the plant or not. Help please identify them for photos.

Third one could be arundinicea, photos not too clear though. Could be Cocksfoot though (dactlis something or other). How tall are they? Arundinicea can get to about 5 ft in ideal conditions. If you've got some tall ones growing alongside, that look the same, you might be in luck Cocksfoot only grows to knee/thigh height.
