aerenchyman.

Brit.

/ɛːˈrɛŋkᵻmə/, U.S.

/ɛˈrɛŋkəmə/

Forms:

α. 1800s– aerenchyma, 1800s– aërenchyma.

β. 1800s– aerenchym Brit. /ɛːˈrɛŋkɪm/, U.S. /ɛˈrɛŋˌkɪm/, 1900s– aerenchyme, 1900s– aërenchyme.

Origin: Formed within English, by compounding; modelled on a German lexical item. Etymons: aero- comb. form, -enchyma comb. form.

Etymology: < aero- comb. form + -enchyma comb. form, after German Aërenchym (H. Schenck 1889, in Jahrb. f. wissensch. Bot. 20 527). Compare French aérenchyme (1898 or earlier).

Botany.

Plant tissue containing large, air-filled intercellular spaces, found chiefly in the roots and stems of bog and aquatic plants.
