Warning: “fuller’s teasel” is used for either or both teasels depending on the source.

Key features:

• receptacle bract shape, flexible or not [these are the short spines throughout the teasel head (info source)]
• involucre bract shape [these are the long spines sprouting from the base]
• leaves widely or narrowly fused around stem
• flower color

The receptacle bracts are the dense bracts dominating the head (one receptacle bract per flower). The involucre bracts are the few much longer bracts subtending the head.
