calyx
Flower's outer whorl
The calyx is the outermost part of a flower, formed by the sepals—the typically green, leaf-like structures that enclose and protect the bud before it opens.
Once the flower blooms, the calyx sits at its base, cupping the petals.
In anatomy, calyx refers to cup-shaped cavities, particularly in the kidney where urine collects.
Plural: calyces or calyxes.
