Herbarium voucher specimens:—Under the name of T. fontanum , there are three herbarium sheets of a single gathering in the Doll’s Bulgarian collection.

Sheet III: Two robust plants with achenes. The material may be homogeneous. Interpretation:— A taxon probably belonging to T . sect. Crocea , different from T. fontanum s. str.
