Anther

Anther, that portion of the stamen of a flowering plant that contains the pollen. It may be compared to the blade of a leaf and to the microsporangium in lower plants. The typical anther is oblong, divided perpendicularly into two lobes, with a midrib or connective. The lobes commonly split longitudinally, and discharge the pollen from the loculus, or chamber within. This cavity results from the fusion of two primitive pollen-sacs. Anthers are usually yellow.
