Abstract

The genus CIRSIUM Adans, one of the genera in Asteraceae, has 250-300 species distributed over the world. According to Flora Iranica (Rechinger) there are 5 sections, 7 subsections, 28 species, 4 subspecies and 10 vrieties in different regions of Iran. This study was carried out on the existing species found in KHORASAN, Which include 10 species. Among CIRSIUM species, 8 species were investigated in detail of SYSTEMATICal point of iew. CIRSIUM congestum Fisch& C.A.Mey.,C Bornmulleri Sint. Ex Bormn, C. strigosum (M.B.) M.B., C, osseticum (Adams) Petrak, C. turkestanicum (Regel) Petrak., C. vulgare (Savi) Ten., Crhizocephalum C.A. Mey., C. arvense (L) Scop.The specimens were collected and were dried with the usual methods of herbarium specimens and different parts of them (organs) were studied with stereomicroscope and drown. This investigated aimed to provide the identification and distribution maps of the CIRSIUM species. The presentation of the relevant keys has been done according to fundamental characters. In this study 62 qualitative and quantitative characters of taxawere recorded for a NUMERICAL TAXONOMY. Finally, the species were analyzed with the help of the software SPSS and through cluster analysis ward's methods. These studies showed that the CIRSIUM species have more differences in leaf are a dominant character in discriminating between the species. For example: in C. congestium and C. turkestanicum the baxial surface of leaf are covered with more and less of spiders web trichoms, and croweded Spiders web trichoms, respectively. The results of Cluster analysis assert the classic classification. For example: The two species, C. strigosum and C. oseticum (Sec. Epitrachys) have more affinity to each other but there are little affinity between the C. congestum (Sect. Pseudepitrachys) and C. rvense (Sect. Cephalonoplos). So, the results proved taxnomic studies are important in SYSTEMATIC of investigated species and through these information which phylogenetic relation of species can be determined.
