Stamens typically consist of a stalk called the filament from Latin filum , meaning thread , and an anther from Ancient Greek anthera , feminine of antheros flowery, from anthos flower , which contains sporangium microsporangia . Anthers are most commonly two lobed and are attached to the filament either at the base or in the middle portion. The sterile tissue between the lobes is called the connective. A typical anther contains four microsporangia. The microsporangia form sacs or pockets locules in the anther. The two separate locules on each side of an anther may fuse into a single locule. Each microsporangium is lined with a nutritive tissue layer called the tapetum and initially contains diploid pollen mother cells. These undergo meiosis to form haploid spores. The spores may remain attached to each other in a tetrad or separate after meiosis. Each microspore then divides mitotically to form an immature Gametophyte microgametophyte called a Pollen pollen grain . The pollen is eventually released by the opening dehiscence of the anther, generally by means of longitudinal slits, but sometimes by pores, as in the Erica heath family Ericaceae , or by valves, as in the barberry family Berberidaceae .
