Summary:In the present paper are described the karyotypes and the morphological traits of the chromosomes of twospecies of Inula: Inula spiraeifolia L. and Inula hirta L. We have used achenes of the two species. After germination theroots were prefixed in 0,2% colchicine, fixed and stained according to Feulgen method. The karyotype of Inulaspiraeifolia L. (2n=16) is highly symmetrical with small length metaphasic chromosomes. All the eight pairs areclassified as median chromosomes. All studied specimens were diploid. We have realized two variants of karyotype forInula hirta L. (2n=16). In both cases the eight pairs are classified as median and submedian chromosomes. Also nopolyploidisation phenomena were observed. As we know, this paper is the first report of karyological analysis of these species in Romania and our results are convergent with the data reported by foreign authors. [PUBLICATION ABSTRACT]
