Frequently Asked Questions
Adnation is the fusion of dissimilar organs (e.g., stamen to petal). Connation is the fusion of similar organs (e.g., stamen to stamen, petal to petal).
No, it is a highly specialised technical term with almost zero usage outside of botany and related biological sciences.
No, the term itself is a noun. The related adjective is 'adnate', and the verb form is 'to adnate' (though this is rarely used).
There isn't a single direct antonym, but 'free' (as in 'free stamens') or 'distinct' describes the lack of adnation.
