PLATE XLVI. 
DICKSONIA PUNCTILOBULA. Kunze. 
SWEET-SCENTED FERN. 
This is the only American species of the genus, and is 
not common in Kentucky, though Prof. Hussey reports it 
as growing abundantly in Edmonson County. I have some 
beautiful specimens from the banks of Silver Creek, Clark 
County, Indiana, only a few miles from Louisville. They 
grow on loose, shaly rocks, apparently without much nour- 
ishment. It may be readily mistaken by the young bota- 
nist for the Lady Fern. But a careful examination of the 
fruit-dots, in well-developed plants, will enable him to iden- 
tify it at once. 
The frond is about two and a half feet high, lanceolate- 
ovate, and twice pinnate. The pinnules are exceedingly 
regular in outline, resembling patterns for decorative de- 
signs. The whole plant is covered with numerous little 
glands which emit, when crushed, a very pleasant odor. 
This fern has a trailing root-stock, and is very difficult to 
transplant, but with care it may be made to grow very well. 
It needs plenty of room in which to develop its graceful 
fronds. 
A piece of a frond, natural size, is shown in the Plate.
