How many stations ofthe filmy fern are there inIllinois? No one knows, The 
station which Miss Strong saw during the first quarter of this century has been lost 
as a result of railroad construction, The total number of known stations in Illinois 
is now nine, The station from which Dr, Steagall made her collection in 1923 is the 
first one from which collections were obtained in Illinois, This station now appears 
on the decline, In the autumn of 1957, two sites were discovered in Hayes Creek 
Canyon. In walking along almost 50 miles of cliff bases since the autumn of 19571 
have found that filmy fern grows in five additional places in Pope County and one in 
Johnson County, Many more miles of cliffs remainto be examined in Pope and John- 
son counties andin Hardin County to the east, No one knows how many more stations 
will be discovered in Illinois by explorations of these cliffs,
