Abstract

In this study; a list of the Centaurea L. taxa kept in (ISTE) “Herbarium of Faculty Pharmacy, University of Istanbul” is given. The genus Centaurea is the third largest genus in terms of species number in Turkey. There are 217 species (146 endemics), 36 subspecies (22 endemics), 28 varieties (16 endemics) totally 255 taxa and endemism ratio is 66.8 %. ISTE has an important Centaurea collection with 146 species (67 endemics), 28 subspecies (18 endemics), 20 varieties (9 endemics) totally 171 taxa (83 endemics). The collection also contains 16 European species. Basic chromosome numbers of the genus were reported as x = 6, 7, 8, 9, 10, 11, 12, 13, 15.
