THE FERNS OF SCOLOPENDRIUM LAKE. 



By Lucien M. Underwood. 



(HAVE often been asked to indicate the species of ferns that 

 grow in the immediate vicinity of Green Lake, near James- 

 ville, Onondaga county, New York, which has posed as the 

 locality furnishing the largest number of species. I refer to that 

 particular "Green Lake" which is located about a mile east of 

 the D., L. & W. station at Jamesville, as the one a similar dis- 

 tance to the west, although better known, is far less interesting. 

 I think all the species will be found within a radius of fifty rods 

 from the margin of the lake or pond, as it is a mere pool in the 

 depression left, doubtless, after the caving in of the roof of a 

 cavern. 



The list is as follows : Polypodium vulgare, Adiantum pe- 

 datum, Pteris aquilina, Pellsea atro purpurea,* Asplenium Tricho- 

 manes, A. angustifolium, A. thelypteroides, A. filix-fcemina, 

 Phyllitis Scolopendrium, Camptosorus rbizophyllus, Phegop- 

 teris hexagonoptera, P. Dryopteris, Dryopteris Thelypteris, 

 D. spinulosa intermedia, D. cristata, D. Goldieana, D. margina- 

 lis, D. acrostichoides, D. Boottii,* Cystopteris bulbifera, C. fra- 

 gilis, Onoclea sensibilis, Dicksonia punctilobula, Osmunda re- 

 galis, O. cinnamomea, Botrychium ternatum,* B. Virginianum. 

 All the species are comparatively common at this station except 

 the three which I have marked with a*; these three I have found 

 only once. 



At "White Lake," an interesting locality about half a mile 

 north of Green Lake, I found a single specimen of Ophioglossum 

 vulgatum; less than half way to the city of Syracuse and within 

 three miles of this Green Lake, on the " Jamesville road," is the 

 original Central New York station for the curious plant that has 

 been referred to Botrychium Lunaria, and on the cliffs near by,
