Lonicera japonica Thunb. 



and white oak, about a mile south of Alcinda in Noble County. This slope 

 bordered a land-locked blueberry swamp and I believe this plant may 

 have been a frequent plant about the swamp before the water level was 

 lowered. The plant grew about 8 feet above the water level. I found this 

 colony in 1916, but when I revisited the place in 1929, although the colony 

 still persisted, it was almost extinct. I searched the border of this swamp 

 for other colonies but failed to find any. 



So far as is known, this plant will soon become extinct in Indiana except 

 in Porter County.
