Azalea lutea L. (Rhododendron calendulaeeum) Flame Azalea. Common on a few 

 hillsides in the immediate vicinity of Sugar Grove. The only station in the 

 state. Persistent and long continued search for it in the southern section of 

 the area during its flowering season has failed to reveal it. It is in imminent 

 danger of extinction and should be protected. 



Rhododendron maximum L. Rhododendron. Abundant in the northern section of the 

 area from Clark's Crossing to Sugar Grove and a little beyond. Also at the 

 "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. 



Kalmia angustifolia L. Sheep Laurel. I have been informed liy trustworthy ob- 

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

 of its habitats, namely the head of Laurel Run, but I have not found it. 

 Neither was it known to Bigelow or Sullivant, nor is there an authentic speci- 

 men from Ohio. 



Oxydendrum arboreum (L.) DC. Sorrel-tree. On the edge of its range. Common. 



Epigaea repens L. Trailing arVjutus. Common.
