DistributionThroughout the Mountains, and sparingly into the Piedmont foothills east to Stokes and Iredell counties. [Note that the BONAP county range map includes V. nudum merged into V. cassinoides as a single species.]

This is a Northern species, ranging from southern Canada south essentially though the mountains to northern GA and AL.
AbundanceThis species is fairly common to common in the higher elevations, and infrequent at low elevations, including the Piedmont foothills.
HabitatThis is a species of a variety of cool, usually moist forests. It is most often found in moist forests and bogs, but it is also found in upland forests (often where rocky) and outcrops.
PhenologyBlooms from late May into June; fruits from August to October.
IdentificationThis is a medium-sized deciduous shrub with opposite leaves, often growing to 6-8 feet tall. It has ovate to nearly elliptic leaves, usually with a narrowed tip, to an average of 3 inches long. Unlike most viburnum species, the leaves have entire to barely visible serrations. Also, the leaves show a very strong, indented, and whitish mid-vein. This shrub might be tricky to identify without reproductive parts; fortunately, during most of the growing season the large slightly rounded cluster of small white flowers at the branch tips, or the clusters of blue-black fruit with a whitish bloom, are usually easily seen.
Taxonomic CommentsThis species is usually considered a species separate from V. nudum, which grows mainly in the Piedmont and Coastal Plain. However, some references do merge them; when that is done, this taxon in some references becomes the nominate variety – V. cassinoides var. cassinoides, or conversely in others – V. nudum var. cassinoides.
