Rhaponticoides amplifolia (Boiss. & Heldr.) M.V. Agab. & Greuter
Notes
Rhaponticoides amplifolia is a taxon originally described as Centaurea amplifolia from Mt Killini (locus classicus, first collected in 1851 by Orphanides), that had been reported also from SE Bulgaria and adjacent NW Turkey (Eren 2007). After clarification of the status of the Bulgarian and Turkish plants these were assigned to Centaurea wagenitziana (= Rhaponticoides wagenitziana), a species new to science which closely resembles Centaurea amplifolia with which it had been confused (Tan et al. 2009). Thus, Rhaponticoides amplifolia is endemic to Greece, known to occur on Mt Killini in N Peloponnisos and on Mt Gymnovouno near Trikala. A record of Centaurea amplifolia from Albania is queried by Tutin & al. (1976) and Barina & al. (2018) and may represent a yet undescribed taxon (Tan et al. 2009).
