Southwestern Virginia to Alabama in the mountains, 
but not occurring above 800m. Named for Prof. Albert 
Ruth, who sent the species to me. At once separated 
from A. arz/olium by its cylindrous calyx, its tube not 
being contracted at the throat as is that of A. artfolium. 
Type locality: Morristown, Tenn.
