downy arrowwood

(Viburnum rafinesqueanum)

               
Overview

Downy arrowwood is a medium-sized shrub that rises on multiple stems from a woody, spreading root system. It occurs in North America east of the Great Plains from Quebec to Manitoba south to South Carolina and Tennessee. It is common in northern and eastern Minnesota, mostly absent in the southwestern quarter of the state. It grows in moderately moist to dry upland woodlands in full sun, partial sun, or deep shade.

There are two varieties of downy arrowwood, rafinesqueanum and affine. The ranges of both varieties appear identical, and many collected specimens have intermediate characteristics. Nevertheless, the varieties are generally, though not universally, accepted. Both varieties occur in Minnesota.

What’s in a Name?
This species was named for the 19th century polymath Constantine Samuel Rafinesque, who made important contributions to botany and zoology. It was published in 1820 as “Viburnum rafinesquianum”. The species epithet is a latinized correctable misspelling of the honoree’s last name. The corrected name is “Viburnum rafinesqueanum”. Many authoritative sources use the corrected spelling, but about the same number use the name as originally published. Which is correct? An argument can be made for either spelling.

Taxonomy
The genus Viburnum was formerly included in the Caprifoliaceae (honeysuckle) family. Based on a molecular phylogeny study published in 2005, it was moved to the Adoxaceae (moschatel) family.
