Negaresh, K. (2020). Lectotypification of Boissier's names Centaurea hyalolepis and C. laxa (Asteraceae, Cardueae). Candollea 75: 145–147. In English, English abstract.

Edmond Boissier (1810–1885) described several taxa in the genus Centaurea L. (Asteraceae), summarized in his Flora orientalis account. Lectotypes are designated here for the two names Centaurea hyalolepis Boiss. (sect. Calcitrapa DC.) and Centaurea laxa Boiss. & Hausskn. (sect. Ammocyanus Boiss.). Lectotypes are kept in the G-BOIS herbarium.
