calues
Calues, also known as calyces or calices, are cup-shaped structures found in various biological contexts. In botany, calyces refer to the outermost whorl of floral leaves, collectively forming the calyx. These sepals, as they are individually called, typically enclose and protect the developing bud. They are often green but can also be colored, mimicking petals in some species. The number, shape, and fusion of sepals vary greatly among different plants, contributing to their classification and identification.
In anatomy, calyces are also found in the kidneys. These are funnel-shaped structures that collect urine produced
