PREP'ACK. 



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 exactly 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 hy 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 :
