Nothofagus pumilio (Poepp. et Endl.)Krasser is a broadleaved deciduous tree that dominates high-elevation forests in the southern Andes.We evaluated the degree to which differences in stomatal density and physiological traits (net assimilation, conductance and water use efficiency)were related to environmental and genetic influences with elevation by comparing plants growing under field and common garden conditions. Low-elevation leaves under field conditions had fewer stomata, although this pattern was not maintained in the common garden. Assimilation rates were >40
