some of the fertile terminal pinnae, which, also, are 
pinnate, each pinna thus simulating a normal frond. 
On one frond there are six terminal pinnae thus meta- 
morphosed. Only one clump of this interesting form 
of Polystichum acrostichoides was found, growing with 
typical plants. 
). DRYOPTERIS HEXAGONOPTERA (Michx.) C. Chr. 
Widely dispersed in moist woods. In Gray’s New 
Manual it is stated that in this species the blades are 
“usually broader than long,” while in D. polypodioides 
they are “‘longer than broad,’ but the statement for 
D. hexagonoptera does not hold in this locality, where 
many of the fronds were longer than broad. 
11. Dryopteris Dryopteris (L.) Christ. The oak 
fern was found in some abundance in a damp ravine, 
growing among moss along with Lycopodium lucidulum. 
In the recent Flora of the Vicinity of New York it is 
stated that in New York this fern is not known south 
of the Catskills, consequently the present record is 4 
slight extension of range. 
Mr. H. Woynar has pointed out in a letter to Mr. 
Maxon, and it also is shown in Christensen’s Supplement 
to the Index Filicum,' that the binary name Dryopteris 
Dryopteris was published before the appearance of the 
second edition of Britton and Brown’s Illustrated Flora, 
where it was proposed as new.? 
12. Dryopreris THELypreris (L.) A. Gray. Com- 
mon in swamps and marshes. 
13. DRYOPTERIS NOVEBORACENSIS (L.) A. Gray. 
Well distributed, but not very abundant, in rich woods. 
14. DRYoOpTERIS MARGINALIS (L.) A. Gray. One of 
the common ferns of this locality. The writer was im- 
pressed by the fact that the fronds were much larger
