12. Hieracium murorum [subsp. tenuiflorum var. pilosiceps] forma molinerae P.Rossi & Zahn in Zahn (1934: 481)

Ind. loc.:—“Limbiate in der Lombardei; Val Molinera und Pioverna in den Alpen von Lecco; Ratsalm ob Welschnofen! Gailtal 500 m ”.

Type:—[ ITALY. Lombardy, Prov. LC] “ Valle Molinera —sponda destra. In luoghi ombrosi rocciosi lungo i margini del sentiero che sale da Prato S. Pietro poco sotto e ad oriente delle rocce «il frate e la monaca», 12 Set 1919, P. Rossi ” (lectotype, designated here: PAV barcode PAV-LOM014952 !) .

Syntype:—[ ITALY. Lombardy, Prov. MB] “ Limbiate , Apr 1923, L. Fenaroli ” ( TR-BOT027322 !) .

Remarks: —We traced two different specimens in PAV and TR, collected respectively by P. Rossi and L. Fenaroli in the localities indicated by Zahn (Val Molinera and Limbiate). Both specimens have determinations handwritten by Zahn. The PAV specimen bears a label handwritten by Zahn dated 1923 with a diagnosis of the new variety (in the label it is called H. murorum L. subsp. tenuiflorum Arv. -Touv. var. molinerae Rossi & Zahn ). The TR specimen bears two labels handwritten by Zahn with his determination. Both specimens are in poor condition, with missing leaves or parts of the leaves. However, the specimen PAV-LOM014952, despite the missing leaves, can safely be considered as the lectotype due to the presence of the original diagnosis by Zahn. The specimen stored in TR remains a syntype.

Current name:— Hieracium tenuiflorum .
