Crithopsis cinsinin tek üyesi olan, C. delileana Schult. Roshev., herbaryum materyalleri, arazi gözlemleri ve laboratuar incelemelerine dayanılarak taksonomik olarak revize edildi. C. delileana’nın 18 populasyonuna ait 90 birey, C. delileana populasyonlarının morfolojik açıdan yapısını ve çeşitliliğini belirlemek amacıyla, Temel Bileşen analizinde kullanıldı. İstatistiksel analizin sonuçları göstermiştir ki; populasyonlar arasındaki varyasyonlar tür içi bir taksonun ayrılmasına izin vermemektedir. İstatistiksel analize ek olarak, güncellenmiş ve genişletilmiş tür tanımı aynı zamanda bu türün dağılım haritası ve vejetatif anatomik karakterleri de verilmiştir

Morphological and anatomical properties of the genus Crithopsis Poaceae in Turkey

Öz

C. delileana Schult. Roshev., the only member of the genus Crithopsis is taxonomically revised on the basis of herbarium materials, field observations, and laboratory examination. Ninety accessions belonging to 18 populations of C. delileana were subjected to Principal Component Analysis in order to determine the variability and the structure of its natural populations of based on morphology. The results of statistical analysis showed that the variability among the populations does not permit to distinguish any intra-specific categories. In addition to the statistical analysis, emended and updated description along with a distribution map of this species and the vegetative anatomical characters are also given
