Plural of epicalyx; a ring of small leaf-like parts that sit just beneath the main flower sepals.
From epi- (upon) + calyces (plural of calyx, the outer flower parts). The prefix indicates these structures sit on top of or outside the main calyx.
Some flowers have a bonus ring of leaf-like structures called epicalyces that make them look even fancier—like nature added extra decorative trim!
