RCN: 6592.    Lectotype(Wagenitz in Rechinger, Fl. Iranica139b: 418. 1980): Herb. Linn. No. 1030.16 ( LINN).   Note:Jeffrey (in Kew Bull.22: 137. 1968) designated material ( "200") in the Clifford herbarium (BM) as lectotype, but there are three sheets associated with species number 20 (Herb. Clifford: 422, Centaurea20 [2 sheets] and 20 δ- 1 sheet). They are not part of a single gathering so Art. 9.15 does not apply, and Wagenitz'sappears to be the first explicit type choice. 2612073138 LINN 1030.16 lectotype
