Identification

Many thanks for the id cicuta58. Can you tell me what distinguished this from Sonchus arvensis and Picris echioides?

Differences

Sonchus arvensis has bigger flowers, less divided leaves and golden glands. Picris echioides is much more bristly with large bracts and has white warts all over.
