 "Written Rock" on Clear Creek and near the head of Laurel Run. Otherwise 

 absent from the southern section although there are multitudes of habitats 

 apparently more suitable for it than those in which it has been found.

 servers that this plant formerly grew in the area and have been directed to one 

 of its habitats, namely the head of I^aurel Run, but E have not found it.
