Composits are often difficult without the photograph of fruit, which normally is not taken unless you are a keen taxonomist. At the same time with just the fruit you can identify the whole plant especially in the group with ligulate heads (kindly see my paper published in 1972, enclosed here). In this case perhaps clue lies in involucre bracts which are in more than two series and bracts are triangular. With ligulate florets only in the It points to Scorzonera. Wild species S. divaricata has zigzag stems and very narrow.

I think you are on the dot!
