and on thehills. If we deduct these three species, the number abso- 
lutely known to be growing in Kentucky is thirty-eight. Four of 
these are not to be found in New York State. They are, Polypodium 
tncanum, Swartz,common South, but not found in the Northern 
States; Asplenium pinnatifidum, Nuttall, which is reported as plenti- 
ful in Kentucky; Asplenium Bradleyt, D. C. Eaton, an extremely 
rare species found only in Tennessee and Kentucky; and 7Zricho- 
manes radicans, Swartz, the Killarney fern, a species widely-diffused 
throughout the world, although of rare occurrence in America, being 
found only in Alabama, Tennessee, and Kentucky. This leaves 
thirty-four species and varieties which are common to New York 
and Kentucky. But has the former State any ferns which do not 
appear in the latter? Let us enumerate them. The following list 
comprises the species and varieties already discovered in this State, 
which are not known in Kentucky.

Here is a list of twenty-two ferns native to New York State, 
which are not found in Kentucky. That is, deducting the four Ken- 
tucky’species not found here, we have eighteen species and varieties 
more than Kentucky, making in all fifty-two ferns which grow in the 
State of New York. No other State in the Union, east of the Mis- 
- sissippi, can show such a list of ferns as this, and in no other are 
Scolopendrium and Woodsia hyperborea known to exist. In one other 
State only, viz., Vermont, has Woodsta glabella been found. Our 
herbarium will verify every species here quoted, except Aspidium 
Fragrans, which Professor Peck found at Lake Avalanche, in the. 
Adirondacks, and Aspidium aculeatum, which he discovered at Lower 
Ausable lake and one other point inthe mountains. Our specimens 
of these species came from points farther west. So far as we are 
aware, no complete list of the New York ferns has been published 
since Paine’s catalogue was issued, and several species have been 
added since that time. The above list comprises all that are now 
known as natives of the State, including, of course, the thirty-four 
species which are common to the two States. Should the time ever 
come when a separate history of our New York ferns shall be writ- 
ten, it will, or at least it ought, include some curious and inter- 
esting bibliography.
