In a process called "'microsporogenesis "', four haploid microspores are produced from each diploid sporogenous cell ( microsporocyte, pollen mother cell or meiocyte ), after meiotic division.

The'lower Asparagales'typically have simultaneous microsporogenesis ( i . e . cell walls develop only after both meiotic divisions ), which appears to be an apomorphy within the monocots, whereas the'core Asparagales'have reverted to successive microsporogenesis ( i . e . cell walls develop after each division ).
