Parts and their functions

• Anther (परागकोश) — Bilobed; each lobe has two theca (dithecous). Four microsporangia (two per lobe) make the pollen.
• Filament (पुतंतु) — Long slender stalk of the stamen; proximal end attached to the thalamus or petal.
• Connective (योजी) — Sterile tissue joining the two anther lobes; it carries the vascular supply from the filament.
• Pollen sac (microsporangium) (पराग कोष (लघुबीजाणुधानी)) — Microsporangia develop into pollen sacs; they run the full length of the anther and are packed with pollen grains.
• Pollen grains (पराग कण) — Male gametophytes formed from microspores inside the pollen sacs.
• Line of dehiscence (स्फुटन रेखा) — Longitudinal groove along which the mature anther splits open (dehisces) to release pollen.
