Hieracium maculatum subsp. leptodermum Zahn (1921: 519). Ind. loc.: “Kleinasien: im Tal Ĝgdere am Olymp!” Lectotype (designated here by Gottschlich): — TURKEY: Bithynia, in regione inferiore montis Keschisch-dagh (Olympi), supra Brussa, in umbrosis vallis Ĝgdere, 200 m, 26 May 1899, J. Bornmüller (Iter Anatolicum tertium, 1899, No. 5257) (B barcode B 10 0484861!) [Fig. 3]. Remarks: —In the protologue Zahn notes: “An melius H. diaphanoidi (= vulgatum-murorum) adscribendum?” In fact, the two plants of the lectotype of Hieracium maculatum subsp. leptodermum show more affinities with H. diaphanoides than with H. maculatum, to which we consequently classify it here: Hieracium diaphanoides subsp. leptodermum (Zahn) Gottschl. & Vogt, comb. nov. Basionym: Hieracium maculatum subsp. leptodermum Zahn (1921: 519) ≡ Hieracium leptodermum (Zahn) P.D.Sell & C.West in Davies (1975: 431).
