/ɔˈtiʃəs/

Origin: Formed within English, by derivation; partly modelled on a German lexical item. Etymons: auto- comb. form¹, -oecious suffix.

Etymology: < auto- comb. form¹ + -oecious suffix, in sense 1 after German autoecisch (1874 in the passage translated in quot. 1882, or earlier; 1866 as autöcisch (which is now the usual form): A. de Bary, in Monatsber. der K. Preussischen Akad. der Wissensch. zu Berlin 1865 32).

1. Mycology. Of parasitic fungi (esp. rusts and smuts): inhabiting the same host throughout their life. Cf. heteroecious adj. at hetero- comb. form .

1882 S. H. Vines tr. J. von Sachs Text-bk. Bot. (ed. 2) 332 Such forms [of parasitic fungi] as these are said to be heterœcious (metœcious), to distinguish them from those..which inhabit the same host throughout their whole life (autœcious [Ger. autoecischen]).

1906 D. McAlpine Rusts Austral. xvii. 55 From the very nature of the case no one has been able to observe an autoecious fungus becoming heteroecious.

1966 McGraw-Hill Encycl. Sci. & Technol. (rev. ed.) XI. 654/2 Autoecious rusts, such as P. asparagi (asparagus rust) complete their life cycle on one species of host.

1999 D. Ingram & N. Robertson Plant Dis. ix. 188 The best known species to plant pathologists is the autoecious Melampsora lini, the flax rust.

2. Botany. Of a bryophyte or its inflorescence: having both male and female sexual organs (antheridia and archegonia), but on separate shoots; also called autoicous. Cf. monoecious adj. 1b.
