Hieracium sulphureum subsp. semipraealtum Bornm. & Zahn in Zahn (1923: 1468). Ind. loc.: “ Wallis: Westlich über Zermatt, 1650 m (Bornmüller)!” Holotype:— SWITZERLAND. Valais: Zermatt, steinige Abhänge oberhalb (westl.) d. Dorfes, 1650 m, 25 June 1914, J. Bornmüller (B barcode B 10 0460362!).— Current name: Pilosella sulphurea (D i ll 1843: 521) Schultz & Schultz Bipontinus (1862: 432). Remarks: —The broad white margins of the involucral bracts and the shorter stem height suggest an influence of Pilosella lactucella, the leaf shape being of P. piloselloides. A distinction at subspecies level is unnecessary for these recent hybrids.
