The present paper deals with chromosome number of five Primula taxa. The studies were carried out plants from the northeast Anatolia (Turkey). The following chromosome numbers have been detected: Primula vulgaris HUDS. subsp. vulgaris 2n = 22, P. vulgaris subsp. sibthorpii (HOFFMANNS) W. W. SM. & FORREST 2n = 22, P. elatior subsp. meyeri (RUPR.) VALENTINE & LAMOND 2n 16, P. megaseifolia BOISS 2n = 18 and P. longipes FREYN & SINT. 2n = 16. The chromosome numbers of four of these five taxa are presented for the first time. The present determination and previous reports of chromosome numbers of the genus exhibited great variation in the basic number.
