Research Notice:  Trillium Speciation in the Smoky Mountains

In 2008 I joined a research project initiated many years ago by Richard 
Vagner, in and around the Great Smoky Mountains National Park.  It is 
concerned with the relationships between species in and around the national 

Two of those species, Trillium simile and T. erectum album, appear to form 
a cline with simile at the foot of the mountains, and erectum album at the 
higher elevations.  We have collected samples of several colonies along the 
cline under our National Park Research Permits.  I think we now have a 
broad sampling of both species in the eastern Tennessee-western North 
Carolina area.

We are seeking collaboration with a laboratory that can carry out DNA 
sequence analysis of these plants with the aim of clarifying their 
relationship.  If anyone wants more information, they should contact me at 
the address below.
