Leaves of Piper hispidum, a shrub native to the lowland tropics of Mexico, have a strong stomatal response to humidity that results in similar rates of water loss under a wide range of leaf-to-air water-vapor concentration gradients. Stomatal conductance of these leaves is insensitive to CO(2) concentration and increases in response to high humidity even in the dark.
胡椒科胡椒属植物的叶子对湿度有强烈的气孔反应，导致在广泛的叶-气水蒸气压浓度梯度下，水分损失率相似。这些叶子的气孔导度对二氧化碳浓度不敏感，即使在黑暗中，也会对高湿度作出响应而增加。
