Term:
Stomatal crypt
Stomatal crypt
Definition:
A pit, usually on the abaxial leaf blade surface, in which the stomates of nearly all species of occur.
A pit, usually on the abaxial leaf blade surface, in which the stomates of nearly all species of occur.
Notes:
In neotropical Lecythidaceae, the stomates of nearly all species have their stomates on the abaxial leaf blade surface (some stomates are found adaxially at least in some species of Gustavia) and sunken in stomatal crypts. In addition some species have abaxial papillae. All of these features are hypothesized to be ways that they reduce evapotranspiration from their leaves and, thus, conserve water.
