28. Hieracium murorum [subsp. glaucoviolascens] forma subbifidum Zahn (1923: 1541)

≡ Hieracium murorum [subsp. glaucoviolascens] subforma subbifidum (Zahn) Zahn (1931: 481) .

Ind. loc.:—[without indication].

Type: —[ ITALY. Lombardy, Prov. LC] “nei castagneti posti appena ad est e sopra Bonzeno fraz. di Bellano ”, 6 Mai 1923, P. Rossi ” (neotype, designated here: PAV barcode PAV-LOM014244 !) .

Remarks: —Zahn described this taxon with an extremely short diagnosis (“vel 0” [referring to glandular hairs on the peduncles]) and without indicating any locality or collections. Later Zahn (1931) reported some localities in Alps of Lecco (V. Erve and Valle della Pioverna unter Taceno), citing specimens collected by P. Rossi. In PAV we could trace four specimens collected by P. Rossi in the Alps of Lecco that bear labels handwritten by Zahn and referred to this taxon (from PAV-LOM014244 to PAV-LOM014247). Although these specimens could not be considered as the original material, they match Zahn’s description and have been certainly seen by Zahn. For these reasons they could be designated as a neotype. We designated the specimen PAV-LOM014244 as a neotype since it consists of two complete and well-developed plants collected in Bonzeno, at the end of Valle della Pioverna, not far from Taceno.

Current name:— Hieracium tenuiflorum .
