|discussion=<p><i>Carthamus creticus</i> has been reported for British Columbia in all recent floras, as <i>C. lanatus</i> subsp. baeticus. It is native to the Mediterranean region.</p><!--
--><p>Apparently an allohexaploid derived by hybridization between <i>Carthamus leucocaulos</i> (2n = 20) and <i>C. lanatus</i> (2n = 44) (M. O. Khidir and P. F. Knowles 1970b), <i>C. creticus</i> is similar to <i>C. lanatus</i> and was treated as a subspecies of the latter (P. Hanelt 1963, 1976).</p><!--
--><p>Most American botanists have recognized this taxon at species rank, using the name <i>Carthamus</i> baeticus ascribed to (Boissier & Reuter) Nyman, based on the assumption that Nyman (Consp. Fl. Eur., 419. 1879) had proposed a new combination at the species level based on Kentrophyllum baeticum Boissier & Reuter. P. Hanelt (1963) used the name <i>C. lanatus</i> subsp. creticus for this taxon and treated both <i>C. creticus</i> and C. baeticus as synonyms. However, Hanelt (1976) substituted <i>C. lanatus</i> subsp. baeticus as the name for the taxon, ascribing the combination to the same Nyman publication. Hanelt (pers. comm.) has indicated that the contradictory nomenclatural citations were a result of Nyman’s peculiar way of presenting taxa that he considered to be subspecies: “in the work of Nyman the small-printed taxa subsumed under a ‘true’ species name and characterized by an asterisk had to be accepted as subspecies.” As a subspecific epithet, baeticus (1879) has nomenclatural priority over creticus (1914), hence Hanelt’s 1976 use of the former.</p><!--
--><p>Like <i>Carthamus lanatus</i>, <i>C. creticus</i> is a noxious weed that can severely degrade infested rangelands.</p>
