microsporangium

microsporangium A sporangium (e.g. in heterosporous (see HETEROSPORY) ferns and the clubmoss Selaginella) that produces numerous minute spores which germinate to produce only male gametophytes. Those pteridophytes that produce them also produce megasporangia containing few (often only 1–4) large spores; these spores germinate to produce the female gametophytes.
