Anne Elliott's photos with the keyword: holds spores

I believe I am correct in saying that this is Equisetum arvense, commonly known as Field Horsetail or Common Horsetail - the spores are contained in this beautiful cone-like strobilus. This macro image was taken on 21 May 2013, NW of Calgary, along the edge of a gravel backroad. I always think that the tiny "plates" look rather like flowers with their "petals".
