890 REPORT OF STATE GEOLOGIST. 



P. ovata L. Mountain Phlox.

 form is of the mountains, and its extension of range into Indiana 

 is questionable. Admitted on herbarium specimens labelled as 

 from "southern Indiana." 



Flowers in June and July. 



Clark (Baird and Taylor); Jefferson. 



P. GLABERRIMA L. Smooth Phlox.
