Doll [as Taraxacum pseudofontanum ] ( JE , no. det. 19264); three plants in flower, two of them belonging to T. vile . Sheet II: Flora von Bulgarien , Rila-Gebirge, Malowitza-Hütte. 16 Jul [19]76, R . Doll ( JE , no. det. 19265), originally determined as T. pseudofontanum vel T. parsennense ; three leaf rosettes, mostly with achenes. They belong to T . sect. Crocea . Sheet III: Flora von Bulgarien , Rila-Gebirge, Musalla-Hütte. 12. 7. [19]76., R . Doll [as Taraxacum pseudofontanum ] ( JE , no. det. 19516). Sheet III contains a single plant with an empty scape and an envelope with achenes; the material is not in a condition to be evaluated. Interpretation:—All the plants we were able to interpret belong to T . sect. Crocea ; one of them can be assigned to T. vile , a species described below. None of the specimens is close to T. pseudofontanum of the Alps.
