Anatomical observations at the S.E.M. have been carried out on Trifolium bivonae Guss., an endemic species occurring in northern Sicily only on flyschoid substrate. In order to clarify possible signs of the plant response to ecological factors, the research has been conducted both by analysing the foliar epidermis and the morphology of the root. The latter seems to play an important role in determining the plant adaptation to the environment.
