    • n calyx In botany, in general, the outer set of the envelops which form the perianth of a flower. It is usually more herbaceous and leaf-like than the corolla, but it is often highly colored and corolla-like, and is sometimes the first to fall. It may form the entire perianth, no corolla being present; or when there are several whorls of envelops, they may so grade into each other that the calyx cannot be strictly separated from the bracts without and the petals within. The parts of a calyx when distinct are called sepals, and it is disepalous, trisepalous, etc., according to their number. When they are more or less coalescent into a cup or tube, it is said to be gamosepalous or monosepalous, and may be regular or irregular, or variously toothed, cleft, or divided, and either free from the ovary or adnate to it.
    • n calyx In human anatomy, one of the cup-like or infundibuliform beginnings of the ureter in the pelvis of the kidney, surrounding the apices of the Malpighian pyramids, each receiving usually more than one pyramid. There are from seven to thirteen such calyces, converging and uniting in three infundibula, which in turn combine to form the pelvis. [In this sense calyx is generally found in the plural form, calyces or (incorrectly) calices.]
