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.
