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

Ind. loc.:—“Val Pioverna; Welschnofen (Huber)”.

Type :—[ ITALY. Trentino Alto-Adige, Prov. BZ] “Italien. Südtirol: Fichtenwald ob Nova Levante; 1250 m; 21 Jul 1927, A. Huber-Morath ” (lectotype, designated here: BASBG barcode BASBG-00280843 [image!]) .

Syntypes:—[ ITALY. Trentino Alto-Adige , Prov. BZ] “Rechtes Ufer des Ratzöler Bachs ob Nova Levante (Welschnofen) ob Bozen; ca. 1350 m; 22 Jul 1927, A. Huber-Morath ” (BASBG-00280844 [image!]) .

Remarks: —Zahn described this form and cited two different localities: Val Pioverna, surely referring to a collection of Pietro Rossi, and Welschnofen (in South Tyrol), referring to a collection of Huber. We could trace no specimen referred to this taxon in PAV where the herbarium of Pietro Rossi is hosted. We supposed that this specimen (as occurred to other sheets) went lost or was completely damaged by insect infestation. Instead, we could trace two specimens in BASBG, where the herbarium of Arthur Huber-Morath is kept. The two specimens were collected in Nova Levante (Südtirol) and bear the handwritten labels of Zahn with the name of the new forma. Both specimens are in poor condition, with missing or damaged leaves. However, the specimen BASBG-00280843 can safely be considered as a lectotype and the other one remains a syntype.

Current name:— Hieracium tenuiflorum .
