Dipsacales
Fragrant tubular blooms of Viburnum carlesii (Korean spice viburnum).
Plants in the order Dipsacales typically have opposite leaves. These leaves are often gland-toothed, though their specific form can vary among the different families and clades within the order. For example, while many members are characterized by this opposite arrangement, some species may exhibit variations, such as the basal cluster of leaves found in the perennial herb muskroot (Adoxa moschatellina).1
