Etymology: "Epicalyx" is a plain technical compound, built from the Greek prefix "epi-", meaning "upon" or "over," and "calyx," the botanical term for the whole ring of sepals that encloses a flower bud. The prefix comes from Ancient Greek "epí," a word with the same basic sense of "on" or "above" that appears in many English scientific coinages. "Calyx" itself was borrowed from Latin and ultimately traces back to a Greek word for a husk or cup-shaped covering. Botanists formed "epicalyx" by placing the prefix on that existing term to name a second ring of small bracts sitting just outside the true calyx, as in the strawberry and many mallows. The word describes the arrangement literally: a set of structures lying "on" the calyx rather than being part of it.
