somewhat scattered plants on the north side of the ravine. In this par- 
ticular, namely, its location on a south-facing slope, this colony is unique 
in the New York area ; but equally peculiar is its occurrence on outcrops of 
Fiddler's Green limestone of the Camillus series, a full hundred feet below 
the horizon of the Onondaga limestone on which all the other colonies of 
this area are located. 
B. Little Lake {Green Lake) Substation. In September, 1866, Paine 
(3) discovered Scolopendrium on the southern slope of the cliff surrounding 
Little Lake, or Green Lake, as it is now known. Maxon (2) states that 
The plant was formerly very abundant but scarcely half a dozen plants may now be 
found, owing to the greed of picnickers. 
A careful search of this region in November, 1920, disclosed a colony 
of forty or more thrifty plants high up on the slope south of the lake. To 
the southeast of the lake, on the west slope of a plunge basin which contains 
water for a short time each spring, is another colony of fifty or more plants. 
Both these colonies are within the Clarke State Reservation. 
Maxon also mentions the occurrence of Scolopendrium in two wooded 
ravines from thirty to forty rods north of the lake. This region will be 
discussed in detail later as the Jamesville Woods substation. It is sufficient 
to say here that it is at the present time the most promising substation of 
the Jamesville area. 
C. Green Pond Substation. Mr. Paine in the same year found Scolo- 
pendrium at Green Pond, a lake similar to Green Lake and located one and 
one half miles east of Jamesville (C, fig. 2). Of this location, Maxon (2) 
reported that the fern grows 
Pretty well up on the sides at the base of the U cliff which surrounds Green Pond. . . . 
The plants from the cleared eastern portion become of small size and winter kill badly. 
At the present time, Scolopendrium is not found at the eastern side of 
the lake; its disappearance from this area is probably due to clearing fol- 
lowed by fire. Beginning almost directly south of the center of the lake, 
the fern occurs very abundantly on the upper part of the slopes along the 
southern and western sides of the lake. In one area about twenty-five 
feet square, ninety plants were counted. Along a part of the cliff top, 
plants in considerable numbers occur on the level ground immediately back 
of the rim; and in the bottom of a shallow plunge basin a few hundred yards 
south of the rim a few small but mature plants were found. 
D. Rock Gorge Substation. This substation was first discovered by 
Maxon in 1900, at which time he reported "125 extremely fine plants 
growing very thriftily." This colony is still in a flourishing condition. 
However, the small colony reported as located ''in a small depression some 
40 rods to the westward and back from the amphitheater" has not been 
rediscovered, although the region has been examined carefully. 
E. West White Lake Substation. Southwest of White Lake, and equi- 
distant from it and Green Pond, lies a large plunge basin in which Scolo-
