Chromosome Numbers in the Some Taxa of Hesperis L. (Brassicaceae) from Turkey

Abstract

Hesperis L. genus belongs to Brassicaceae family and has 27 species in Turkey. In this study, chromosome numbers were
defined for the first time in five taxa of Hesperis L. which grows up naturally. These taxa are Hesperis schischkinii Tzvelev, H.
anatolica A. Duran, H. pendula DC. subsp. dirmilensis A. Duran, H. özcelikii A. Duran and H. aspera Fourn., according to their
floristic order. Diploid chromosome numbers of Hesperis schischkinii, H. anatolica and H. aspera species were counted as 2n = 14,
while those of H. pendula subsp. dirmilensis and H. özcelikii taxa were 2n = 12. There was only one double satellited metaphase
chromosome in H. anatolica among these five Hesperis taxa.
