florets, and flat appendages ending in membranous margins, often
with a brown spot at the base of each appendage. Centaurea
heldreichii and C. litochorea have procumbent or ascending (not

tomentose hairs. Moreover, C. heldreichii has pink-purplish and
C. litochorea bright, lemon-yellow, not creamy-white florets.
