PREFACE, 
The object of this Catalogue is to furnish a compact and accessible record 
of the plants actually reported as growing spontaneously within one hun- 
dred miles of New York, and especially to provide a convenient check-list by 
means of which to secure from the botanists of the region a series of fresh and 
detailed reports as to the plants of their respective localities, to the end that a 
complete list of our Flora, with full and accurate stations for all forms of es- 
pecial interest, may ultimately be prepared. Botanists engaging in this work 
are requested to observe the following rules: 
1.—Indicate degrees of prevalence by the following terms:—‘‘ Very com- 
mon,” ‘‘common,” ‘‘abundant,’”’ ‘‘frequent,” ‘‘not rare,” ‘‘rare,” ‘‘very 
rare,”’ ‘‘only one plant observed.”’ 
2.—Report the principal stations for all rare or local plants, indicating the 
locality as exaetly as possible and giving the direction and distance from the 
nearest railway station. Precise stations for plants so rare as to be liable to be 
exterminated by indiscriminate collection, should, however, not be given. 
3.—Note dates of commencement and end of flowering thus: April 10— 
May 15. 
4.—In all cases of doubtful identity forward specimens to the Committee 
for verification. 
5.—Return the Catalogue when called for by the Committee with as many 
herbarium specimens of the plants reported as can conveniently be furnished 
for deposit in the Club Herbarium. 
6.—Address all communications to Justus F. Poggenburg, Chairman, 
Committee on Local Flora, Torrey Botanical Club, Columbia College, New 
York City. 
While the territory covered by this Catalogue is, in a general way, bound- 
ed by a circle of one hundred miles radius from the city of New York, the 
Committee has found it expedient to include the whole of New Jersey and 
Connecticut and of those counties of New York and Pennsylvania crossed by 
the circle. The boundary thus becomes in reality a very irregular line, but 
reference to the maps will at once show where it lies. 
A large majority of the plants here enumerated have been personally col- 
lected by members of the Club and are represented by authentic specimens in 
its Herbarium. The publications which have aided in the compilation are as 
follows :
