Abstract: Studies were conducted to assess the diversity of anatomical adaptations of leaves in the genus Eucalyptus (family Myrtaceae) from the Faisalabad region. Thicker epidermis in E. alba Reinw. ex Blume and E. maculata Hook., are the adaptations to water limited environments like drought and salinity. Large cortical cell in E. microtheca F. Muell., and E. botryoides Sm., are the indication of their wide distribution in a variety of different environmental conditions. Eucalyptus crebra F. Muell., E. maculata Hook., and E. microtheca F. Muell., with significantly larger vascular tissue were the better adaptation to a variety of environment types. There was a great variation in leaf anatomical characteristics among Eucalyptus species collected from the Faisalabad region.
