The plural or a collection of extremely small honeycomb-like cellular structures, representing the finest level of microscopic botanical organization.
From multiple Latin diminutive layers: favus → favella → favellilid- → -ia (plural). This represents the extreme end of Latin's ability to create increasingly specific terminology by stacking diminutive suffixes, used only in the most precise scientific descriptions.
Favellilidia is basically the limit of how many times you can make something 'smaller' in Latin before the word gets ridiculous—it's three levels of 'small' stacked on top of 'honeycomb.' Scientists eventually stopped naming like this because it got confusing even for them!
