Abstract Plantago albicans measurements of leaf area, leaf length, leaf width, increase in leaf area in young, fully expanded and old leaves in addition to leaf dry weights were carried out along two seasons. The first season was drier than the second. Correlation coefficients between these leaf measurements and plant leaf water content and climatic parameters indicated that drought not only decreased the plant leaf area and leaf dry weight but did also changes in the leaf morphology. Leaf width showed significantly negative correlation with climatic parameters. The produced leaves at the dry season were thin, longer and attained more hairs. They were also partially folded on the upper side. Leaf age decreased greatly but the activity of the apical bud and hence cell division was not affected with drought. Dry weight per unit leaf area increased also with drought.
