26. Hieracium murorum [subsp. tenuiflorum] forma sinuosifrondiforme Zahn (1931: 480)

Ind. loc.:—“Iseo-See; Gröden 1400 m; Genua; Portofino; […] an der Axenstrasse”.

Type:—[ ITALY, Lombardy, Prov. BS] “ Pisogne , 6 May 1921, L. Fenaroli ” (lectotype, designated here: TR barcode TR-BOT027298b !) .

Remarks:—Although no information about collectors was given in the protologue, we could trace six specimens in TR collected by Fenaroli and determined by Zahn. The specimens (TR-BOT027296a–b, TR-BOT027296a–b, TR-BOT027298a–b) were collected in Groane di Limbiate (in Lombardy) in 1923 and in Pisogne near Iseo Lake in 1921. The locality Groane di Limbiate is cited several times in Zahn (1931) as the lower altitude where H. tenuiflorum was recorded (150 m a.s.l.). However, since there is a clear reference in the protologue to specimens collected near Iseo Lake, we could safely consider original material only the collection of Fenaroli from this area. There are two sheets in this collection. On the first (TR-BOT027298a), leaves of the specimen are missing and severely damaged. On the second (TR-BOT027298b), there is a complete plant with several basal leaves that matches Zahn’s original description.

Current name:— Hieracium tenuiflorum .
