Shoot dimorphism enables <i>Sequoia sempervirens</i> to separate requirements for foliar water uptake and photosynthesis

Shoot dimorphism gives tall Sequoia trees the capacity to absorb up to 48 kg H₂ O h^-1 during the first hour of leaf wetting, ameliorating water stress while presumably maintaining high photosynthetic capacity year round. Geographic variation in shoot dimorphism suggests that plasticity in shoot-type distribution and leaf surface traits helps Sequoia maintain a dominate presence in both wet and dry forests.
