Microsporogenesis and microgametogenesis in Jacaranda mimosifolia (Bignoniaceae)

The development of the anther wall in Jacaranda mimosifolia is Dicotyledonous type. The tapetum is secretory and dimorphic. The microspore tetrads are tetrahedral and the pollen grains are two-celled at the shedding stage. Concurrent with the dissolution of the tapetal cell walls, a new membrane is...
