What does apogamous mean?
Apogamous is a technical adjective in botany and mycology describing development or reproduction that occurs without gamete fusion, the process known as apogamy. In a fern, for example, an apogamous sporophyte may arise directly from gametophytic tissue without fertilization. In certain fungi, apogamous fruiting similarly bypasses the sexual nuclear processes normally associated with reproduction. The word comes from Greek roots meaning 'away from' and 'marriage,' a literal acknowledgment that the usual fusion of reproductive cells has been bypassed. It is not simply a synonym for every form of asexual reproduction: apogamy is a specific developmental route, especially important in studies of ferns and fungi. The term is uncommon outside scientific and specialist contexts, but it precisely identifies the absence of fertilization and makes the reproductive mechanism unmistakable.
adjectiveBotany and mycology: Developing or reproducing by apogamy, without the fusion of gametes.
- Developing or reproducing without the fusion of gametes, especially in ferns and other plants or in certain fungi.
"The apogamous sporophyte developed without fertilization."
"The apogamous sporophyte developed without fertilization."
"Researchers reported apogamous fruiting in cultures of the fungus."
Apogamy literally means 'away from marriage': a new generation can arise without the usual union of gametes.

Where does apogamous come from?
Apogamous was formed from apogamy plus the adjective suffix -ous. Its underlying elements are Greek apó, meaning 'away from,' and gamos, meaning 'marriage,' preserved in the combining form -gamy; the terminology therefore describes development 'away from' gamete fusion. Related forms such as monogamous, polygamous, and endogamous retain the same Greek element but concern one, multiple, or internal unions respectively.

How apogamous is actually used
A rare technical term used chiefly in botanical and mycological literature. It is not a general synonym for all forms of asexual reproduction, because apogamy identifies a particular developmental process involving the absence of gamete fusion.
Easily confused with apogamous
Apogamy is the noun naming the reproductive process, whereas apogamous is the adjective describing something that develops or reproduces by that process.
