In which of the following plants sunken stomata are found : -Sunken stomata lie in pits or depressions (stomatal crypts) lined with hairs. They reduce water loss by keeping a layer of moist air over the stoma.
They are a xerophytic adaptation, found in Nerium (oleander), Pinus and Cycas. In Nerium the leaf has multiple epidermis and sunken stomata in crypts.
Hydrilla is a submerged hydrophyte with no functional stomata; mango and guava are mesophytes.
So sunken stomata are found in Nerium.
