IPA: /loʊˌkjuːlɪˈsaɪdəl/
KK: /loʊˌkjuːlɪˈsaɪdəl/
Relating to a type of plant fruit that splits open along the walls between its compartments to release seeds.
The loculicidal fruits of the iris release their seeds when they mature.
Loculicidal is formed from "loculus" (meaning small place or compartment) and "caedere" (meaning to cut). The word describes the act of cutting open a small compartment, typically referring to the way certain fruits release their seeds.
Think of a 'small compartment' ('loculus') being 'cut' open ('caedere') to release seeds — that's what loculicidal means.
