density, other trees distributed by wind or bird may not then 

 become naturally planted. 



In the course of three summers on the island only three ferns 

 have been found, and as might be expected, these are species 

 independent of tree shade. The species are; the lady fern, the 

 hay scented fern, and the marsh fern. There is a possibility 

 that some of the thickets and boggy places may harbor some 

 of the low growing forms like Ophioglossom or the smaller forms 

 of Botrychium, but so far these have not been seen.

Goldie's Fern {Dryopteris Goldieana) 



As the Torrey Botanical Club contemplates taking the Dec- 

 oration Day Field Trip this year to Branchville, New Jersey, 

 it may be of interest to note that there is an excellent station 

 in that region for the rather scarce but beautiful fern, Dryopteris 

 Goldieana. 



Although this fern has rather a wide distribution, it is 

 apparently never plentiful anywhere, and in Britton's Catalogue 

 of Plants of New Jersey, only three stations are recorded for 

 the state. None of these are in Sussex County. 



Scarcely more than a hundred yards from the hotel, known as 

 "The Pines," near Branchville, there is a limestone rock or 

 boulder, probably ten feet across, covered with Goldie's fern. 

 Around the edge of this rock and near it, are also growing many 

 fine plants of this species. 



This station for Goldie's fern may be familiar to others but 

 I did not know of it until I came across the plants last August.
