Type:— WU, no. det. 8943, lectotype (see Kirschner & Štěpánek 1997: 92)

Doll (1978: 643):—Listed from Bulgaria without locality specification.

Herbarium voucher specimens:—Under the name of T. fontanum , there are three herbarium sheets of a single gathering in the Doll’s Bulgarian collection. They are labelled as Flora von Bulgarien, Rila-Gebirge, Borovez, Sessellift, ca. 1600 m. 11 Jul [19]76. R. Doll [as Taraxacum fontanum ] ( JE, no. det. 19517). Sheet I: Four plants with fruits (two of them with remnants of florets, pollen irregular). Sheet II: Four imperfectly preserved plants in fruit (florets in a separate envelope: pollen irregular). 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. (mainly in the outer phyllary and achene characters).
