Abstract
In this study, the stem anatomy of nine Crepis (Asteraceae) taxa was described for the first time from Türkiye. The anatomical data obtained were evaluated in terms of taxonomy with analysis of variance and principal components analysis. The stem mainly consists of a layer epidermis, parenchymatous cortex, collateral vascular bundles, and parenchymatous pith in all taxa examined. Glandular or non-glandular trichomes are found in the epidermal cells of the stem in some species examined. Even though all taxa examined have similar stem anatomy, quantitative traits such as the length or width of the anatomical characters significantly vary among the taxa. In particular, the xylem thickness considerably differs among the taxa studied, according to the results of analysis of variance. Besides, the xylem is thicker in caulescent species than in scapigerous taxa. According to the results of the principal components analysis, the xylem thickness and the epidermis cell length explain most of the total variation with about 82% value among the studied taxa. These results show that xylem thickness and epidermis cell length have a high taxonomic value.

Abstract
Bu çalışmada, dokuz Crepis (Asteraceae) taksonunun gövde anatomisi ilk kez Türkiye’den tanımlandı. Elde edilen anatomik veriler, varyans analizi ve temel bileşenler analizi ile taksonomik yönden değerlendirildi. İncelenen tüm taksonlarda gövde, başlıca tek tabakalı epidermis, parenkimatik korteks, kollateral iletim demetleri ve parenkimatik özden oluşmaktadır. İncelenen bazı türlerde, gövdenin epidermal hüclerinde salgı veya salgısız tüyler bulunur. İncelenen tüm taksonlar benzer gövde anatomisine sahip olmakla birlikte, anatomik karakterlerin uzunluk veya genişlik gibi kantitatif özellikleri, taksonlar arasında önemli ölçüde değişir. Özellikle, ksilem kalınlığı taksonlar arasında oldukça farklıdır. Bununla birlikte, ksilem, gövdeli türlerde, skaplı taksonlara göre daha kalındır. Temel bileşenler analiz sonuçlarına göre, ksilem kalınlığı ve epidermis hücresi uzunluğu yaklaşık %82 değeri ile çalışılan taksonlar arasındaki varyasyonun çoğunu açıklar. Bu sonuçlar, ksilem kalınlığı ve epidermis hücresi uzunluğunun yüksek bir taksonomik değere sahip olduğunu gösterir.
