24. Hieracium murorum [subsp. tenuiflorum var. macrocephalum] forma reductum Zahn (1934: 482)

Ind. loc.:—“Prato di San Pietro im Val Molinera”.

Type:—[ ITALY. Lombardy, Prov. LC] “ Valle Molinera sponda destra lungo i margini del sentiero che sale da Prato S. Pietro sotto e ad est delle rocce «il frate e la monaca», 12 Set 1919, P. Rossi ” (lectotype, designated here: PAV barcode PAV-LOM015020 !) .

Remarks:—We traced a single specimen collected in the locus classicus by P. Rossi and deposited in PAV.Although the label handwritten by Zahn did not mention the name of the form, the short diagnosis present on the label matches with the diagnosis stated in the protologue. Moreover, the two individuals on the sheet are characterized by a reduced size compared to the other collection. We here designate PAV-LOM015020 as a lectotype of the name.

Current name:— Hieracium tenuiflorum .
