with the persistence of the species in all its described stations and including 
its virtual re establishment at the Green Lake substation, lead to the con- 
clusion that Scolopendrium is at the present time becoming more abundant. 
Summary 
1. All described stations for Scolopendrium vulgare Sm. in the central 
New York area have been located, and the fern has been found in greater 
or less abundance at each. 
2. Two new substations for the species have been discovered in the 
Jamesville area. 
3. The number of individual plants in the six colonies of the Jamesville 
Woods substation was determined in 1916 and again in 1920. Com- 
parison of the data shows that Scolopendrium is becoming more abundant.
