They are found in cavities, called stomatal crypts in Nerium oleander (non-succulent xerophyte). In Ericales, they are located in grooves that are covered in epidermal hair. So, "Stomatal crypts" is the right response. WebThe crypt is a contiguous pocket of epithelial cells at the base of the villus, in which intestinal stem cells (ISCs) are periodically activated to produce progenitor or transit amplifying (TA) cells which are committed to produce mature cell lineages [43,44,45].
