Adoxaceae, Moschatel or Muskroot Family
(Previously Caprifoliaceae, Honeysuckle Family)

The Adoxaceae also called the Moschatel or Muskroot family has opposite simple leaves with entire margins often toothed or lobed. Typical flowers have 5 petals or less common 4 petals. The flowers usually in a cymose inflorescence and the fruits are a drupe.

Adoxaceae species were originally placed in the Caprifoliaceae or Honeysuckle Family which now includes Sambucus, the Elderberries and Viburnum, popular cultivated ornamental plants with showy fragrant flowers. The shift to Adoxaceae from Caprifoliaceae is based on molecular evidence.

The Adoxaceae is a small family containing four genera with less than 200 species.
