Credited as growing only as far south as New Jersey. After 
two years exploration in the mountains of North Carolina and 
Virginia, it can be safely asserted that there it is the prevailing 
viburnum and grows with equal vigor on exposed mountain 
tops and in sheltered valleys. The species reaches greater de- 
velopment in the Southern Alleghenies than it does in the North.*

The specimens from this locality are a little more pubescent 
than usual, but are clearly the species to which they have been 
referred.
