aetheogam

== English == === Alternative forms === aëtheogam === Etymology === From Ancient Greek ἀήθης (aḗthēs, “unusual”) + γάμος (gámos, “marriage”). === Pronunciation === (Received Pronunciation) enPR: ā.ēʹthĭōgăm, IPA(key): /eɪˈiːθɪəʊɡæm/, === Noun === aetheogam (plural aetheogams) (botany) A cryptogam; a plant of the obsolete taxonomic class Cryptogamia, having neither stamina nor pistils, and therefore no proper flowers, such as an alga, fern, fungus, lichen or moss. ==== Usage notes ==== Being derived from the two vowels ἀή (aḗ) (alpha-eta: aē), rather than the diphthong αἰ (ai) (alpha-iota: ai), the initial ae- of aetheogam can only properly be written as two separate letters (ae), with a diaeresis atop the e (as aëtheogam) being optional; the spellings *ætheogam and *etheogam are, therefore, erroneous. ==== Synonyms ==== cryptogam ==== Derived terms ==== aetheogamous (botany) ==== References ====
