wiki Knautia arvensis

[BubikolRamios]

If you check 'Illustrationen', no. 2 is namely not Knautia arvensis. At least leaf part differs from other ilustrations.
Any opinion ?

Maybe Michael can explain what "Knautia arvensis Duby" actually refers to - I couldn't find the source of that name, only this page: https://zenodo.org/records/4373045 .

Anyway, don't trust that Wikipedia's article images are correct. There is the "Wikimedia Foundation" where people upload images to under whatever name they think appropriate, and Wikipedia authors can search the database for "matching" images for their articles. Often enough neither image uploaders nor article authors have the expertise to verify that images really show what they think. Botanical articles are full of mis-identified images because of this mechanism of double cluelessness.

Correcting the image tags in the Wikimedia Foundation is a pain: You also have to edit all articles (in all languages) that use the mislabeled image.
