Viorne

The viornes are Arbrisseau X or small Arbre S pertaining to the kind Viburnum . This kind, formerly classified among the Caprifoliacées, forms today part of the family of the Adoxacées, arranged in the order of the Dipsacales by classification APG II (whereas classification APG I was satisfied to locate it in the euasterid II, without including it in an order).

They are shrubs frequently planted in the gardens for the decorative aspect of their Fleur S and their Fruit S, the latter often being very appreciated by the birds. One counts some between 150 and 220 species in the world.

The name viburnum , also written viburna , indicated already the viorne among Romans.

The rejections, very rectilinear were often used to make barrels of arrows.
