Abstract
The present study aims to revise systematically some species of the genus Galium in Libya, to examine the biosystematic variability of this genus. Five widely distributed species were considered , viz., Galium murale (L.) All., G. tricornutum Dandy, G. aparine L., G. setaceum Lam., and G. verrucosum Huds. The results showed a great systematic variation among the studied species depending on DELTA software and SEM techniques, as well as factorial analysis using PCA . The relationship between the soil variables and the studied populations of Galium species was assessed by application of PCA. Fourteen flavonoid compounds were detected in five Galium species . The flavonoid patterns showed a predominant of quercetin-3-rutinoside, while the other compounds were variable in quality, quantity and in their distribution among the investigated samples
