rare on Staten Island, having been previously reported from but two 

 localities, in one of which, the Clove Lake swamp, it has been since 

 exterminated." My first find of this plant on the Island was in 1903, 

 when I climbed with some difficulty over standing water and secured a 

 specimen at the base of a tree stump in a swamp above Reed's Basket 

 Willow Swamp. Since then a few plants have been found in various 

 places, viz., Linoleumville, Bull's Head, New Springville, Richmond, 

 Great Kills, Eltingville, Huguenot, Bradley Road, Darcey's Woods 

 and Silver Lake. 



25. Dryopteris Clintoniaria (D. C. Eaton). — The Clinton fern was 

 originally reported from " Clove Lake Swamp. Sparingly." I have 

 found it near South Avenue, in Darcey's Woods, near New Spring- 

 ville, and back of Richmond. 



This fern is intermediate in character between the D. cristata and 

 D. Goldieana (Hook.) A. Gray, and it has been allowed to pass as a 

 variety of the former, as first described by Professor Eaton. It differs 

 from D. cristata in being larger, broader in proportion to length, hav- 

 ing stipe more scaly, pinnae more slender pointed, pinnules more falcate, 

 and especially in having the sort near the viidvein. This latter charac- 

 teristic alone ought to be sufBcient to give this fern specific rank. Its 

 resemblances to D. Goliiexna seem to me usually more apparent than 

 to D. cristata. It diffsrsfrom D. Gjldieana in being usually narrower 

 in outline, in the more horizontal position of the pinnae, in having the 

 pinnules less falcate and the stipe less scaly, and the. pimtae broadest at 

 the base. 



I have usually found Goldie's fern in the same pieces of woodland 

 as the Clinton fern; so also the crested fern. This fact and the fact 

 that it is intermediate between the other two suggest that the Clinton 

 fern might have originated as a hybrid, and that it stands in a relation 

 to these similar to that of Boott's fern in relation to D. cristata and 

 D. spimdosa. 



26. Dryopteris Goldieana (Hook.) A. Gra}'. — Goldie's fern was first 

 reported from near South Avenue in the Proceedings of Nov. 14, 1903 

 (vol. ix, p. 2). I have found it also near New Springville (2 places) 

 and in Darcey's Woods. Mr. Davis discovered it in a swamp back of 

 Richmond on one of our joint excursions. 



27. Dryopteris marginalis (L.) A. Gray. — ^The marginal shield fern 

 or evergreen wood fern is met with occasionally in our deeper woods, 

 more especially near New Springville and Richmond. It is much 

 prized for greens to go with cut flowers, and thus it has become more 

 rare than formerly, when it was reported common. Last summer the
