Tue following Catalogue is intended to embra¢e the Phenogamous Plants 
and Ferns, growing spontaneously, within a circuit of 10 miles about Troy. 
Nearly all of them have been examined by ourselves within the last five or 
six years. A few which we have not seen, and some, the names of which 
are not decided, are marked with a ? after the specific name. We have add- 
ed the popular characters of the Plants, and some brief remarks on their medi- 
cinal properties. 
We are indebted to Prof. Earon for valuable information, while preparing 
this Catalogue. |! 
In 1819, the Troy Lyceum of Natural History appointed Prof. A. Eaton, 
and Dr. Grorcr Marvin, a committee to make a Catalogue of the Plants 
growing in the vicinity of Troy. A manuscript copy of a Catalogue, con~ 
taining 774 species, was deposited in the Lyceum, by the committee. This 
Catalogue was mislaid, and was not found unti] preparations had been made 
for publishing the one now offered.
