Adoxa moschatellina (moschatel, five-faced bishop, hollowroot, muskroot, townhall clock, tuberous crowfoot) is an herbaceous perennial flowering plant in the family Adoxaceae. It is the sole member of the genus Adoxa. It grows throughout Europe, Asia, and North America, in hedgerows, cool forests, at low altitudes in the far north, to high altitudes in mountains in the south of its range. The plant and its flowers have a musk-like scent, which it emits towards evening when the dew falls. If the plant is bruised this scent disappears. In Europe, it flowers in April and May.
