A Collector’s List of New Jersey Ferns 
MACY CARHART 
The following list represents collections made by the 
writer in the vicinity of Keyport and in other parts of 
New Jersey. Seventy-nine different forms are included, 
of which sixteen are in the genera Equisetum, Lycopodium, 
Selaginella and Isoetes, leaving the number of ferns at 
sixty-three. The list includes all but four of the fifty 
fern species recorded from New Jersey in Norman Tay- 
lor’s recently published Flora of the Vicinity of New 
York and to a certain extent supplements that work, 
which takes no account of varieties and gives no localities 
at which the hybrids mentioned have actually been 
found. One of these hybrids, named here as Dryopteris 
Clintoniana x cristata, has never been regularly described, ' 
but the plant is fairly distinct and not difficult to recog- 
nize. The plants mentioned in the list are ail represented 
by herbarium specimens.
