17. Hieracium tenuiflorum var. perincisum Arvet-Touvet & Briquet in Briquet (1899: 141)

≡ Hieracium murorum [subsp. tenuiflorum] var. subincisodentatum Zahn (1924: 65) , nom. illeg. superfl.

≡ Hieracium murorum [subsp. tenuiflorum] forma perincisum (Arv.-Touv. & Briq.) Zahn (1931: 479) .

Ind. loc.:—“PE [= Préalpes orientales]. Versant S. du col de Vernaz, 1500–1900 m ”.

Type:—[ France, Dép. Haute Savoie] “ Col de Vernaz (ou de Lachau ) versant S, 1500–1900 m, 5 Aug 1897, J. Briquet ” (lectotype, designated here: G barcode G00392503 [image!]) .

Remarks:—This variety was published by Arvet-Touvet in Briquet (1899) with a short description in French: “ La var. perincisum se distingue du type par ses feuilles incisées-pectinées, les intérieures lancéolées et lounguement acuminées au sommet ” [The var. perincisum is distinguished from the type by its incised-pectinate leaves, the interiors lanceolate and long-acuminate at the apex]. We could trace in G one specimen collected by Briquet in 1897 that bears five different handwritten labels. The first (top right) handwritten by Briquet himself stated the new combination with the information on the collection site and date; the other two on the right seem to be handwritten by Arvet-Touvet but make no mention of the new variety. The two labels on the left are two subsequent (1923) labels handwritten by Zahn, which contained the description of the variety H. murorum subsp. tenuiflorum var. subincisodentatum . The text in the label perfectly matches the protologue of the variety subincisodentatum ( Zahn 1924) . We consider this specimen as a lectotype of H. tenuiflorum var. perincisum .

Current name:— Hieracium tenuiflorum .
