Remarks: —The lectotype bears the handwritten Latin description by Zahn. The specimens in B (barcodes B 10 0448745, B 10 0093064, B 10 0093065, B 10 0460375, B 10 0460376, B 10 0460377) from Bornmüller´s collection can be considered as isolectotypes, even if Bornmüller failed to mention “Ellrich” on the labels in some cases. All specimens belong to Hieracium murorum subsp. chloroprasinum Zahn , described by Zahn in Zobel (1920), a taxon not rare in the Harz mountains. The type kept in MNVD has recently been studied.
