{synonym}
A <microsporangium> is a <sporangium> in which <microspores> are produced. In a <heterosporous> <plant>, those <microspores> develop into male <gametophytes>; production of <sperm> is a later step.
In a <flowering> <plant>, the <anther> contains <microsporangia>. Distinguishing the enclosing structure, the <microspore> and the mature <pollen> grain prevents several different developmental stages from being treated as synonyms.
