We use the Linnaean Binomial Nomenclature system which divides an organism into more specific “bins” starting with Divisions, Kingdoms, Phylum. Class, Order, Family, Genus and Species. The term binomial refers to the use of a genus and species name to designate a specific population of organisms that can breed and produce viable, fertile offspring. BTW, Division is a relatively new category.
Since stomata are affected by [CO2] and water vapor content of the air, an environment with high water vapor content (water potential) and high CO2 levels will likely have the highest #of stomata. I.e. when plants have readily available water source and ample CO2 in order to maximize photosynthesis. As far as geographic environment I think it varies quite a bit and there are competing hypotheses from what I understand
C X-inactivation "switches off" one of the X chromosomes.
