Abstract
Three species ofEuphorbia (E. granulata, E. prostrata andE. hirta) exhibited both morphological and physiological adaptations in dry environmental conditions. High bound water, thick cuticle, dense hair covering and low stomatal index are some of the survival adaptations they developed under water stress conditions of the Indian arid zone.
