Both MEYER (2003b: 75) and AL-SHEHBAZ (2014: 43) listed the holotype in G-BOIS. The duplicate at W was listed by MEYER (2003b), though a search for it was unsuccessful.

Labels of the G, GOET, K, and P duplicates have the species name as Thlaspi oxyceras Boiss., but that combination was published by HEDGE (1965).
