ABSTRACT:
Background: The objective of this work was to study of epidermal cells and stomatal behavior (during day and night) of Mammillaria. The genus Mammillaria is a most popular and morphologically variable genus in the Cactaceae. The genus distributed all over the world; plants are specially cultivated in gardens as ornamental spp. and xerophytic in nature.  They are called globular cacti.

Results and Conclusion: Many epidermal characters like the number of epidermal cells (per microfield), size of epidermal cells, number of stomata (per microfield), size of stomata (during day and night), number of crystals and stomatal index were studied in five species of Mammillaria i.e., Mammillaria baumii, M. comptotricha, M. rekoi, M. prolifera and M. magnimamma.

All selected species have a very interesting stomatal morphology and differ from each other in many characters.
