"Stomatal clustering," an abnormal stomatal patterning that is formed by two or more stomata in the leaf epidermis, has been reported in more than 60 species of terrestrial plants. According to the characters and distributional pattern, two different types of stomatal clusters were identified, However, calculation of R-values in 16 different plant species showed that the classical method in spatial ecology study could not distinguish between these two types of clusters. Therefore, to classify them, the term "contiguous cluster" and "non-contiguous cluster" were introduced. Their formation and ecological significance were also discussed. In order to study whether stomatal clustering occurs in response to the environment, Vicia faba L. were cultivated under different water/salinity levels. Epidermis bioassay was conducted 2 weeks after the treatment. The results showed that drought and salt stresses significantly increased the stomatal density and stomatal index. More importantly, the occurrences of contiguous stomatal clustering also raised along the drought/salt gradients. The result suggests that the stomatal clustering is correlated with environmental signals. It could serve as a new marker for environmental adaptation in terrestrial plants.
