Syntypes:—[ ITALY, Lombardy, Prov. LC] “Loc. Lierna . Sui muri lungo la via del lago, nel tratto che si estende dal capoluogo (Villa) alla frazione Grumo, 5 Jun 1923, P. Rossi ” ( PAV-LOM014308 ) ; [ Italy, Lombardy] “Lierna. Lungo il lago: margine destro della strada provinciale nel tratto dalla frazione Villa alla villa Manzoni 5 Jun 1923. P.

Remarks:—We found three specimens stored in PAV.All of them are irremediably damaged, with leaves, stems, and capitula broken or lost. One specimen (PAV-LOM014308) is composed of single leaves and stem fragments, enclosed in a paper bag. Labels of these specimens, handwritten by Zahn, have a statement of the locality and collection date. Moreover, we traced a specimen in Fenaroli Herbarium (TR-BOT027352). The specimen bears a label handwritten by Zahn which comes from the same locality as cited in the protologue. The specimen was collected by P. Rossi and determined by Zahn. For this reason, we can assume that this specimen belongs to an original collection made by P. Rossi and was donated or exchanged with Fenaroli, and we can consider this specimen as part of the original material. Because of its good condition, we designated the specimen in TR as a lectotype of the name H. murorum var. marchii .

Current name:— Hieracium tenuiflorum .
