An epicalyx, an additional whorl around the calyx of a single flower, is a modification of bracteoles. In other words, the epicalyx is a "group of bracts resembling a calyx" or "bracteoles forming a whorl outer to the calyx". It is a calyx-like extra whorl of floral appendages. They are present in family "Malvaceae", the "Hibiscus" family. "Fragaria" (strawberries) may or may not have an epicalyx.
