How China’s tallest tree cope with height?
Through analyzing the leaf morphological and anatomical
structures as well as 13C at different heights of
Wangtian tree (Parashorea chinensis), the tallest
broadleaved tree known in China, He et al. shows in this
issue that the leaf structures and 13C differ significantly along the vertical gradient and the top-crown leaves exhibit xeromorphic characteristics. These observations indicate that top-crown leaves endure a relatively high water defi
