    This shouldn't be too much of a problem as Carduus pycnophalus grows in the area where I reside. Carduus tenuiflorus is to be found growing in N.Italy! As one can see from the photographs, the leaves and stem are greyish, almost as if there is a spider's web over the leaves. Perhaps I made a mistake in the identification. As Carduus tenuiflorus can reach a height of 100 cm. Where as Carduus pycnophalus can reach 120 cm in height. The specimen that I photographed C.pycno. was easily over 120 cm tall.
    Appreciate an ID and I thank you in advance.

    I am having problems uploading, then sending, of my photographs

    @duffy, I'm not sure what you mean by the two steps (uploading, then sending). Uploading to the forum? Are you using the Upload a File button? Well, don't answer here - could you describe your problems in the thread on

    Plant heights in most field guides are... guidelines. There are always exceptions, and also the possibility of a polypoloid with hybrid vigour.
