In this study, relationships among 6 species of Festuca-Lolium complex were assessed using trnH-psbA sequences. Based on the results of this study Lolium is monophyletic. Also, a cluster including Lolium and Festuca subgen. Schedonorus and F. gigantea can be monophyletic. The results support transferring Festuca subgen. Schedonorus into the genus Lolium as a new combination that was proposed by Darbyshire. The trnH-psbA sequences support transfering Festuca gigantea from Festuca subgen. Drymenthele into Festuca subgen. Schedonorus sect. Plantynia.

This study was concerned with the phenetic relationships of Lolium s.l. (including Festuca subgen. Schedonorus) using flavonoids spot profiles and quantitative morphological characters. Measurement of morphological characters and densitometry of flavonoids spots and their profile plots were performed by using calibrated digital images and ImageJ software package. Multivariate analyses (clustering and ordination) performed by using NTSYS-pc software package. Each species was described based on its flavonoid spot profile, and Rf values and percentage of each spot in the corresponding profile were reported. Variation in flavonoid spot profiles of Lolium rigidum, L. perenne and Festuca pratensis revealed that flavonoids spot profiles revealed that they may be useful characters for further studying the variations within the species level. Cluster analysis of qu...

Cluster analysis of quantitative morphological characters separated the species in well defined groups and further separated L. persicum population Ardabil from other L. persicum populations. Separation of F. arundinacea populations into two distinct groups was also interesting which suggested that the existence of two forms of this species in Iran is probable.
