Systematically comparasions on the anatomical properties of some Jurinea cass. (Asteraceae) species

Jurinea Cass. belongs to Asteraceae family. In this thesis, species of J. consanguinea DC., J. alpigena K. Koch, J. mollis (L.) Rchb., J. macrocalathia K. Koch., J. turcica B.Dogan & A.Duran sp. nov., J. pontica Hausskn. & Freyn ex Hausskn., J. pulchella DC., J. kilaea Azn., J. stoechadifolia DC., J. cypria Boiss., J. macrocephala DC., J. aucherana DC., J. ramulosa Boiss. & Hausskn., J. brevicaulis Boiss., J. cataonica Boiss. & Hausskn. and J. ancyrensis Bornm. have been studied at the point of view of their stem anatomies.The purpose of this study was to find out the relations among 16 species of Jurinea genus.In anatomical studies, cross-sections were taken by microtom from the stem. Xylem were stained to red by safranin, but paranchima was stained to green by fast green.In cross-sections, from the outside to the inside the folowing tissues occur: Cuticle, unilayer epidermis, cortex, vascular bundles and pith. It was seen the differences in vascular bundle numbers and arrangements among the species.Key Words: Jurinea, stem anatomy, Asteraceae
