IPA: /ˈɛpɪˌkeɪlɪks/
KK: /ˈɛpɪˌkeɪlɪks/
A group of leaf-like structures that surround and protect the flower, similar to the outer part of a flower called the calyx.
The epicalyx of the hibiscus flower adds an extra layer of beauty and protection.
Epicalyx is formed from "epi-" (meaning upon or over) and "calyx" (from Greek "kalyx", meaning husk or covering). The word refers to a structure that is situated upon or over the calyx of a flower, serving as an additional protective layer.
Think of something that is 'upon' ('epi-') the 'covering' ('calyx') of a flower — that's what epicalyx means.
