Palynological study of Jurinea (Asteraceae) and related genera from flora of Iran
Jurinea turcica B.Doǧan & A.Duran sp. nova (Asteraceae) is described and illustrated from North-West Anatolia, Turkey. It is closely related to J. macrocalathia and also an endemic. Diagnostic morphological characters of J. turcica from closely similar taxa are discussed. The pollen characteristics and achene surface morphology of J. turcica and J. macrocalathia are examined by SEM. It is diploid with the chromosome number of 2n = 34.
