Brit.

/ˌəʊəspəˈran(d)ʒɪəm/, U.S.

/ˌoʊoʊspoʊˈræn(d)ʒiəm/

Inflections: Plural oosporangia.

Forms: 1800s– oosporangium, 1900s– oösporangium.

Origin: Formed within English, by compounding; modelled on a Latin lexical item. Etymons: oo- comb. form, sporangium n.

Etymology: < oo- comb. form + sporangium n., after scientific Latin oosporangium (G. Thuret Ann. Sci. Nat (Bot.) (1850) 14 235, or earlier).

Botany.

Originally: a unilocular sporangium of certain brown algae. Later: a megasporangium; (also) a capsule containing an oospore.
